In this episode of Fighting Matters, Stephan Kesting of Grapplearts and Jeff Shaw of Bellingham BJJ sit down with clinical psychologist, author, and BJJ black belt Dr. David Ley to challenge everything you think you know about gender.  
  
Is “alpha male” behavior really about dominance and strength? Or is it just bad psychology wrapped in influencer hype? Dr. Ley breaks down the biological, psychological, and cultural science behind gender norms, toxic masculinity, and the emotional hunger many men bring to the Jiu-Jitsu mat.  
  
From PowerSlap to Jordan Peterson to NoFap, we explore how pseudoscience and insecurity get weaponized—and how grappling can offer men a healthier, evidence-based path forward.
