My thoughts here revolve more around personal responsibility. If an escalation like the one described occurs, it marks the end of a development during which opportunities for resolution were missed. I've been playing in bands for decades and wouldn't even consider playing with people who have problematic personalities. You often notice these things quite early on. Because my own mental health is important to me, I don't expose myself to such unhealthy dynamics. Therefore, it would never even get to the point where someone could criticize or even yell at me on stage.
