Well, fightin' words do not JUSTIFY physical violence. I don't argue with the motivation, and can't say how I would have acted in the same situation, but I am not going to condone the violent response. It's still assault. Question back to you... do you think there are situations where someone's words or expressions are a legitimate incitement to violence? Interested to hear them.
Well, yeah. If someone calls me a Jew b*stard to my face, that qualifies; if someone uses the n word to an African American, that qualifies. And, the shirt, IMO, also qualifies.
