How to Identify "Active Clubs" in BJJ

The UFC Freedom 250 debacle

In this episode of Fighting Matters, Jeff Shaw is joined by Jesse Walker, Mike Mahaffey, and Stephan Kesting to take apart UFC Freedom 250, the card being staged on the White House South Lawn on June 14th. Four martial artists who spent decades loving this sport walk through why an event at the people's house, held on the president's birthday and billed as a celebration of America's 250th, leaves them cold. They get into the spectacle, the money, the sportswashing angle, and the version of this card that could have meant something. ⸻ 🔗 Links Mentioned: - Old Bastard BJJ Pride Month Fundraiser — https://patreon.com/oldbastardbjj [https://patreon.com/oldbastardbjj] - Salus Center — https://www.saluscenter.org [https://www.saluscenter.org] - Growing Veterans — https://growingveterans.org [https://growingveterans.org] ⸻ 👥 Featuring: - Jeff Shaw — https://bellinghambjj.com [https://bellinghambjj.com] - Jesse Walker — https://roughhandsbjj.com [https://roughhandsbjj.com] - Mike Mahaffey — https://instagram.com/oldbastardbjj [https://instagram.com/oldbastardbjj] - Stephan Kesting — https://grapplearts.com [https://grapplearts.com] ⸻ 🧠 Topics Discussed: - Why a UFC card at the White House reads as fascist spectacle - The June 14th birthday timing and the "America 250" cover story - The "keep politics out of sports" double standard - Empty seats, military tickets, and who foots the bill - Cage fights as diplomacy, and what sportswashing really is - Theodore Roosevelt, immigration, and the event this could have been - What MMA lost when it stopped being outsider art ⸻ 📖 Chapters: 00:00 — Introducing the panel 02:40 — Fascism, spectacle, and macho posturing 04:30 — A birthday dressed as an anniversary 07:05 — Theater and a regime that believes in nothing 10:16 — Dead enthusiasm and a tourism slump 14:09 — Empty seats, military tickets, and June heat 16:32 — Rogan ringside and bread and circuses 18:53 — Who pays, and who gets held accountable 25:41 — But Roosevelt did it too 30:06 — Cage fights as diplomacy and sportswashing 34:53 — How you'd do it right, and why they can't 40:13 — Can this work at the White House at all? 46:18 — Outsider art and what's been lost

Anti-Trans Hate Is a UFC Marketing Strategy

In this episode of Fighting Matters, Steve Kwan talks with Mike Mahaffey of Old Bastard BJJ about the trans hate pouring out of combat sports, and the fighters who have figured out it pays. They start with Sean Strickland's AI video of himself beating up a trans woman, then get into why guys like Strickland and Jake Shields keep posting this stuff: it riles up a certain kind of fan, and that attention is the product. Recorded during Pride Month, it is also about what the jiu-jitsu community owes its trans members, who take the brunt of this. 🔗 Links Mentioned: - Old Bastard BJJ on Patreon (buy "Introduction to Base" in June, all proceeds go to the Salus Center) — https://patreon.com/oldbastardbjj [https://patreon.com/oldbastardbjj] - Salus Center, Lansing — https://www.saluscenter.org [https://www.saluscenter.org] ⸻ 👥 Featuring: - Steve Kwan — https://bjjmentalmodels.com [https://bjjmentalmodels.com] - Mike Mahaffey — https://instagram.com/oldbastardbjj [https://instagram.com/oldbastardbjj] ⸻ 🧠 Topics Discussed: - Sean Strickland's anti-trans AI video and the threat behind it - How the "fairness in women's sports" debate gets used as cover for violence - Active clubs, fascism, and the far right's foothold in fight sports - Mike's advocacy work and the threats it brings - The harassment trans grapplers face just for showing up to train - Why fighters profit from anti-trans content - Why "keep politics out of jiu-jitsu" is a cop-out - Raising a trans daughter and changing minds through storytelling ⸻ 📖 Chapters: 00:00 — Welcome and why a Pride episode 02:26 — The Strickland video and the "fairness" cover 08:47 — Active clubs and the far right in fight sports 11:20 — Mike's advocacy and the threats it draws 17:46 — Spite-based activism and trans grapplers under attack 22:30 — Why fighters monetize trans hate 30:04 — Staying neutral is a choice, and the politics myth 34:08 — Pride, gender, and changing norms 40:17 — You don't have to get it to defend it 42:36 — Mike on supporting your trans friends and family 47:35 — Why martial artists have to speak up 51:06 — Mike's fundraiser for the Salus Center

Why did UFC BJJ let Mikey compete with a staph infection?

In this episode of the Fighting Matters podcast, Steve Kwan is joined by Jeff Shaw of Bellingham BJJ, Mike Mahaffey of Old Bastard BJJ, and Dr. Clayton Green, a board-certified dermatologist and BJJ practitioner. They get into what happened at UFC BJJ when Mikey Musumeci defended his title against Kevin Dantzler with an active staph infection, went back to the hospital right after the match, and defended the decision by saying he had covered the infection with spats. The conversation covers why staph is more dangerous than people realize, how the UFC has stopped fights like this before but didn't this time, and what gyms and competitors can actually do to be safer. 🔗 Links Mentioned: - NFHS Wrestling Skin Lesion Form — https://a-us.storyblok.com/f/1022696/x/87b3155d73/2025-26-nfhs-wrestling-skin-lesion-form-final-april-2025.pdf [https://a-us.storyblok.com/f/1022696/x/87b3155d73/2025-26-nfhs-wrestling-skin-lesion-form-final-april-2025.pdf] ⸻ 👥 Featuring: - Steve Kwan — https://bjjmentalmodels.com [https://bjjmentalmodels.com] - Jeff Shaw — https://bellinghambjj.com [https://bellinghambjj.com] - Mike Mahaffey — https://www.instagram.com/oldbastardbjj [https://www.instagram.com/oldbastardbjj] - Dr. Clayton Green ⸻ 🧠 Topics Discussed: - What happened at UFC BJJ and Mikey's hospital readmission - Why "I covered it with spats" isn't a defense - How close Ben Askren came to dying from MRSA - Whether BJJ is losing community knowledge about infection risk - How pandemic-era science denial is showing up in jiu-jitsu - How the UFC stopped fights like this before, and didn't this time - The wrestling skin check form and how gyms can use it - Institutional accountability vs dogpiling on the athlete ⸻ 📖 Chapters: 00:00 — Introducing the panel 02:39 — What happened at UFC BJJ 05:16 — Spats aren't condoms 10:09 — How dangerous staph actually is 18:08 — Are we losing community knowledge about infection risk? 25:21 — Why didn't the UFC stop this? 26:34 — Pandemic-era science denial in BJJ 33:13 — The wrestling skin check form 36:45 — How gyms model and enforce safer behavior 40:48 — Advice for young competitors under pressure 50:22 — Institutional accountability vs dogpiling the athlete 53:02 — Closing thoughts

How Jiu-Jitsu Survives the AI Era

In this episode of Fighting Matters, Steve Kwan is joined again by Dr. David Riedman: 17-year jiu-jitsu practitioner, MIT-trained data analyst, and PhD researcher whose dissertation focused on measuring the accuracy of large language model outputs. David is also the author of the Riedman Report, one of the most popular Substacks on risk, AI, education, and security. The conversation is broken into three parts. Part one is a broad explanation of what modern AI actually is and how it works. Part two covers the cultural and social impact of AI on public life. Part three is about how AI will affect the business of jiu-jitsu and the people who train and run gyms. Steve walks out of the conversation with a take he didn't expect: martial artists may be in a stronger position than people working in tech. ⸻ 🔗 Links Mentioned: - The Riedman Report — https://riedmanreport.substack.com [https://riedmanreport.substack.com] - K-12 School Shooting Database — https://k12ssdb.org [https://k12ssdb.org] ⸻ 👥 Featuring: - Steve Kwan — https://bjjmentalmodels.com [https://bjjmentalmodels.com] - Dr. David Riedman — https://riedmanreport.substack.com [https://riedmanreport.substack.com] ⸻ 🧠 Topics Discussed: - Why LLMs don't actually think, and why that matters - The political split on AI adoption and why both sides are partially right - Where AI genuinely helps a small business and where it creates risk - Model drift, context dilution, and how guardrails break down in long conversations - Why AI tutorials and AI video can't teach jiu-jitsu - What it means for a sport without a unified registry when anyone can fabricate credentials - The trillion-dollar lock-in: why we may be stuck with LLMs even if they don't work - Why human-service work like coaching may be more durable than tech work ⸻ 📖 Chapters: 00:00 — Reintroducing Dr. David Riedman 03:25 — PART 1: What modern AI actually is 15:39 — Why a confident-looking LLM output can still be wrong 23:12 — PART 2: The cultural and social impact of AI 35:09 — When the stakes are too high to outsource 42:09 — When AI is used to plan a war 50:54 — Model drift and how the guardrails erode 58:23 — PART 3: AI and the business of jiu-jitsu 01:03:11 — Automating the soul out of your gym 01:14:20 — The trillion-dollar bet on a tool that may not work 01:22:06 — Three futures and none of them are good 01:29:46 — What gym owners and practitioners should actually do
