In this episode of Fighting Matters, Steve Kwan of BJJ Mental Models, Jesse Walker of Rough Hands BJJ, and Mike Mahaffey of Old Bastard BJJ welcome special guest Eric Muntz to tackle one of the most self-destructive tendencies of the political left: the purity trap.

We’ve talked plenty about the dangers of the far right, but tonight we turn the mirror on ourselves. Why do progressive movements so often collapse into circular firing squads, language policing, and purity tests that alienate allies and shrink coalitions? And how can we build the kind of durable, inclusive movements needed to actually fight back against authoritarianism?

From South Park jokes and punk rock roots, to the paradox of control in Jiu-Jitsu and the paradox of tolerance in politics, this conversation draws surprising parallels between martial arts and activism. The takeaway: no coalition survives if everyone must already be perfect to join it.
