Practicing Vulnerability: A Black Man’s Struggle toward Understanding and Belonging




From an early age, most boys absorb the message—whether stated directly or modeled by the men and women in their lives—that to be a man is to be tough.

I learned that early. In my household, crying got me grounded or spanked, or both. And, of course, I was expected not to cry about the punishment. The older I got, the less that punishment mattered. I became numb to the pain, cut off from the hurt and sadness I felt. Eventually, I learned to express myself through anger.

In the community I grew up in, showing weakness in any form was frowned upon. Any boy considered soft would be bullied or catch a beating from their peers. My community taught me how to express myself through violence.

I was never taught to feel the full range of emotions, to understand when those feelings were appropriate, or how to express myself. This left me isolated and unable to deal with some of the most basic human experiences in a healthy way. Sadness and grief were off limits.

To this day, it’s hard for me to cry in front of other men. I have come a long way toward emotional health, but I still struggle and often am reminded that I am not as fully healed as I thought. I know that I have to continue to confront the physical, emotional and sexual abuse I experienced as a child, but knowing this intellectually does not make it easier.

I recently had a conversation with a friend that helped me better understand myself. Our lifer group (men facing life-without-parole sentences) made a decision to support proposed legislation that I disagreed with. The details aren’t crucial, but I thought the compromise law being endorsed would cut out too many people who should have benefited. I strongly believe that we should work as hard as possible to support each other, that we don’t leave anyone behind. I thought that was the commitment of the group, something we had all agreed on, but somewhere along the line something had changed. I felt betrayed and hurt because of the group’s decision. Rather than dig in for hard conversations, I isolated myself and pushed away from my friend and the group. Instead of confronting the disagreement, I retreated.

That may sound familiar in today’s polarized political culture, and those same conflicts occur in prison. Philosophical and political differences, which could be an invitation to conversation, can quickly alienate us from each other when no one wants to be the one who budges. I see now how this happened with my friend. He was confused about my reaction until I finally apologized. Admitting I had been unfair to him required me to be vulnerable, which wasn’t easy.

I still think the group made the wrong choice, but I had been wrong to blame, and then cut off, my friend. I don’t have to abandon my values to recognize that others may have good reasons to disagree. We can face those differences and maintain a close friendship. In the end we agree on a lot more than we disagree on.

All that may seem obvious, but it was another reminder of how that always-be-tough training still affects me. I know that I can’t escape my past trauma, but sometimes it’s easier to walk away than face it, even though I know that hurt and pain are likely to come out in unhealthy ways. It usually begins with something I’m angry about. Healthy anger? It feels like every time I have seen someone angry, it ended in violence.

Again, it may seem obvious, but as an adult I have had to learn that violence is not the only way I can react when my feelings get hurt. That’s not easy in prison, where building trust through healthy dialogue is always difficult. I live with others who come from similar backgrounds and have untreated trauma, just like me. That’s a combustible environment. When I want to stick to my values, it can feel as if any move I make is dangerous, and my guard goes up. New patterns take time.

In his book The Four Pivots, Shawn Ginwright analyzes the forces that make it so hard for men, and black men in particular, to be vulnerable. To get comfortable with emotional disclosure and risk taking, we have to be there for each other when things get really hard. Ginwright points out that surviving racism can harden us, a reaction reinforced by the toxic form of masculinity that is so common in patriarchal societies.

I have had to confront not only my own fear of vulnerability but the same fear in the men around me. Like so many struggles, this one is almost impossible to win on our own.

A Man’s Worth


Author’s note: This piece is dedicated to the memory of Angie Tibbs, who was a dear friend and also my editor at DV for many years. Her light still shines in the souls of the justice seekers and the peace makers to light our way through these dark times.

It is easier for a camel to pass through the eye of a needle than for a rich man to enter the Kingdom of God. – Matthew 19:24

I recently had the misfortune of seeing a video clip of Stephen Miller, one of the chief architects operating within the lawless Trump regime, presenting Trump as a great man, ostensibly because he is a billionaire who is accruing still more wealth while presiding as the head of state in the US. The core tenet of Miller’s shallow assessment is that a person’s value to society can only be commodified and measured in dollars and cents. This suggests that Miller knows the price of everything but the value of nothing.

In contrast to Miller, I contend that money making by hook or crook, almost entirely the latter, is not evidence of greatness or character and that a litany of malfeasance and felonies are certainly not a measure of a man’s worth. But under capitalism, where money and material possessions are God, the prince of darkness sits upon a golden toilet and empties his bowels, in much the same way as the rest of us, but for whom porcelain is good enough.

The American oligarchs behave as if having money is somehow equated with the highest virtues of humanity and therefore worthy of respect and adulation, if not also emulation. But from my working-class perspective, neither Trump nor Miller possess a scintilla of grace or virtue. Indeed, no member of Trump’s corrupt cabinet has ever been accused of manifesting empathy or morality.

Trump and his acolytes are at best sociopaths, and at worst, psychopaths. They obviously enjoy hurting people, and they appear to become aroused while they watch their victim’s suffering, as their deaths play out in places like Minnesota and Venezuela. These are not admirable traits, and they are not evidence of greatness, but rather of depravity. Neither are they evidence of psychological health, strength and character. They are symptoms of weakness, disease and rot.

In the eyes of more righteous and humble ordinary men and women, Stephen Miller and Donald Trump are grotesque monsters. They are sick, soulless men and a danger to the entire world, the lowest of the low, and vilest of the vile. All the money in the world cannot buy them character, integrity, respect or forgiveness for their crimes against humanity. When their death arrives, as it inevitably will, few are those who are debased enough to mourn their passing. Many will celebrate. Their legacy is corruption and a trail of corpses. History will not remember them kindly.

If these character flaws are evidence of wealth, the kind that cannot be corrupted by moth and rust, then give me dignified poverty. Decent people have no desire to emulate ignorant, greedy, power-hungry fools. The oligarch gods suffer from arrested psychological development, but they imagine themselves to be Gods among mortal men. Their wealth is accumulated on the backs of the working class. Coping with reality and deep introspection are not among their strengths.

Men like Donald Trump and Stephen Miller carry bibles and they speak the language of Christianity, but in truth, Christ would be ashamed of such company. It was men like Trump and Miller that crucified Christ. They are antichrists dressed in the garments of Christianity, preaching the false gospel of prosperity, pretending to be what they are not and can never be. Their despicable deeds speak for themselves and that will be their legacy.

Mired in the quicksand of self-aggrandizement and delusion, both men are examples of mediocrity and rot. They are dead on the inside; ghouls dressed in the finest garments that money can buy, much like Jeffrey Epstein was. Fine clothes are but an outer garment that conceals the naked emperor that lurks underneath. Clothes cannot conceal who and what the emperor really is. In the words of songwriter Leonard Cohen: “Everybody knows.” That is, everybody but him.

The real value of a man cannot be measured in dollars and cents or in gold and silver, or digital currencies. A man’s true worth is measured by his service to his fellow man and woman, and it is cloaked in humility. Men like Alex Pretti, who became a working-class martyr a few days ago, is of greater worth to humanity than a million Donald Trumps and Stephen Millers. Remember that Christ was a pauper. He was, as Thoreau said of himself, rich without damage to his poverty. Superfluous wealth is an impediment to growth, not an asset to psychological development and spiritual evolution.

In the same way, the value of Renee Nicole Good to humanity far exceeds the value of all the oligarchs combined. She, too, was martyred by Trump’s goon squad in the streets of Minnesota. She wore a crown of innocence that her killers cannot buy at any price.

While it is true that the voice of Alex Pretti and Renee Nicole Good have been silenced, the collective voice of resistance to tyranny rings loud and clear. Martyrdom brings people together and amplifies their power. Their ideas, their example, lives on in us. The final deeds of Alex Pretti, who died courageously protecting a woman from physical abuse by armed thugs, lights the way through the darkness of oppression and despair. That light can never be extinguished. Alex Pretti’s extrajudicial execution has inspired organized opposition to tyranny. Let his death be not in vain.

Whatever lies are sold to us in the corporate propaganda mills, the people in the streets know who the real domestic terrorists are.

KRICT demonstrates 100kg per day sustainable aviation fuel production from landfill gas



Joint research by KRICT and EN2CORE Technology validates an integrated process that produces aviation fuel from abundant landfill gas—more readily available than used cooking oil—demonstrating the feasibility of decentralized SAF production

The aviation industry accounts for a significant share of global carbon emissions. In response, the international community is expanding mandatory use of Sustainable Aviation Fuel (SAF), which is produced from organic waste or biomass and is expected to significantly reduce greenhouse gas emissions compared to conventional fossil-based jet fuel. However, high production costs remain a major challenge, leading some airlines in Europe and Japan to pass SAF-related costs on to consumers.

Against this backdrop, a research team led by Dr. Yun-Jo Lee at the Korea Research Institute of Chemical Technology (KRICT), in collaboration with EN2CORE Technology Co., Ltd., has successfully demonstrated an integrated process that converts landfill gas generated from organic waste—such as food waste—into aviation fuel.

Currently, the refining industry mainly produces SAF from used cooking oil. However, used cooking oil is limited in supply and is also used for other applications such as biodiesel, making it relatively expensive and difficult to secure in large quantities. In contrast, landfill gas generated from food waste and livestock manure is abundant and inexpensive. This study represents the first domestic demonstration of aviation fuel production using landfill gas as the primary feedstock.

Producing aviation fuel from landfill gas requires overcoming two major challenges: purifying the gas to obtain suitable intermediates and improving the efficiency of converting gaseous intermediates into liquid fuels. The research team addressed these challenges by developing an integrated process encompassing landfill gas pretreatment, syngas production, and catalytic conversion of syngas into liquid fuels.

EN2CORE Technology was responsible for the upstream processes. Landfill gas collected from waste disposal sites is desulfurized and treated using membrane-based separation to reduce excess carbon dioxide. The purified gas is then converted into synthesis gas—containing carbon monoxide and hydrogen—using a proprietary plasma reforming reactor, and subsequently supplied to KRICT.

KRICT applied the Fischer–Tropsch process to convert the gaseous syngas into liquid fuels. In this process, hydrogen and carbon react on a catalyst surface to form hydrocarbon chains. Hydrocarbons of appropriate chain length become liquid fuels, while longer chains form solid byproducts such as wax. By employing zeolite- and cobalt-based catalysts, KRICT significantly improved selectivity toward liquid fuels rather than solid byproducts.

A key innovation of this work is the application of a microchannel reactor. Excessive heat generation during aviation fuel synthesis can damage catalysts and reduce process stability. The microchannel reactor developed by the team features alternating layers of catalyst and coolant channels, enabling rapid heat removal and suppression of thermal runaway. Through integrated and modular design, the reactor volume was reduced by up to one-tenth compared to conventional systems. Production capacity can be expanded simply by adding modules.

For demonstration purposes, the team constructed an integrated pilot facility on a landfill site in Dalseong-gun, Daegu. The facility, approximately 100 square meters in size and comparable to a two-story detached house, successfully produced 100 kg of sustainable aviation fuel per day, achieving a liquid fuel selectivity exceeding 75 percent. The team is currently optimizing long-term operation conditions and further enhancing catalyst and reactor performance.

This achievement demonstrates the potential to convert everyday waste-derived gases from food waste and sewage sludge into high-value aviation fuel. Moreover, it shows that aviation fuel production—previously limited to large-scale centralized plants—can be realized at local landfills or small waste treatment facilities. The technology is therefore expected to contribute to the establishment of decentralized SAF production systems and strengthen the competitiveness of Korea’s SAF industry.

The research team noted that the work is significant in securing an integrated process technology that converts organic waste into high-value fuels. KRICT President Young-Kuk Lee stated that the technology has strong potential to become a representative solution capable of achieving both carbon neutrality and a circular economy.

The development of two catalysts enabling selective production of liquid fuels was published as an inside cover article in ACS Catalysis (November 2025) and in Fuel (January 2026).

Facility for Converting Landfill Gas into Syngas (CO and H₂) Suitable for SAF Production

Unlike conventional systems, the use of miniaturized and modular microchannel reactors enables facility deployment at a small scale.

As concerns rise about the effects of tiny plastic particles on human health, Flinders University researchers have led new research on whether nanoplastics can accumulate or cause damage in kidneys – our body’s major blood filtering system.

Their study, published in high-ranking international journal Cell Biology and Toxicology, calls for more investigations into the long-term risks, warning that high nanoplastics (NPs) particle ‘burden’ could seriously compromise kidney cell health and function.  

“The findings demonstrate that while lower concentrations of NPs (less than 1 micron or 0.001mm in diameter) may not result in immediate toxicity to the kidney cells, particularly in terms of short-term exposure, higher burdens can compromise overall cell health and function, causing changes to the cell shape, survival and cell regulation,” says first author Hayden Gillings, a PhD Candidate in Nanoplastics and Health at Flinders University.

“The results also indicate that the effects are influenced not only by concentration but also by polymer composition and particle size, with some combinations inducing significant cellular changes even at relatively low doses,” says Mr Gillings, from the College of Science and Engineering.

The laboratory study tested kidney cells with varying concentrations and sized NPs, sourced from commonly used polymers – polystyrene (PS), poly(methyl methacrylate) or ‘PMMA,’ and polyethylene (PE).

It was supported by medical scientists from Monash University as well as Flinders University’s College of Medicine and Public Health. 

The research team says sustained or repeated damage to regulatory kidney cells could impair kidney function, reduce filtration efficiency, clearance capacity, and lead to their potential buildup of NPs in kidney tissue over time.  

With these plastics most commonly present all around in the environment, the study emphasises the need for further real-world long-term investigations into the effects of concentration, size, polymer types and chemical additives.

“Such studies should also explore biological outcomes, including potential DNA damage and long-term functional consequences, to fully assess the risks posed by environmental NPs to kidney health and systemic exposure,” adds Flinders University Associate Professor Melanie MacGregor, an ARC Future Fellow and Matthew Flinders Fellow in Chemistry.

Associate Professor MacGregor, who leads the Nano and Microplastics Research Consortium at Flinders University,  says rising levels of plastic waste are breaking down in every part of Earth’s land, sea and air, leading to the proliferation of microplastic (pieces less than 5mm) and nanoplastic pollution posing a risk to all lifeforms.

“Millions of tonnes of microplastics can break down into even smaller nanoplastic particles and lead to chemical leakages,” she says. 

“Tougher measures should be taken to reduce the release of chemicals and pollutants such as volatile organic compounds and micro- and nanoplastics to the environment, food chain and living organisms – both during production and after use.”

Kidney Health Australia says 2.7 million Australians, or about 1 in 7 Australians aged over 18 years old, are living with signs of kidney disease. Diabetes, hypertension and other conditions can reduce kidney function, leading to waste build-up in your body, and harmful impact on health.
