He was sharing a yarn about a Hispanic friend in Arizona pulled over "for no reason" and continued with the "systemic racism" tripe, preaching to the kids, with the social justice warrior band teacher giving the amens. I asked him in front of the kids if our justice system is then systemically sexist against men, because our prisons are over 90% male. Silence. Amid all that insanity at the time, I wanted the kids to hear a skeptical voice and to hear it challenged.
I'm glad you brought this up, because you folks depend on intimidating people into silence. That is becoming less and less effective, and you guys know it.
