No, you teach them to be smart and not act on just emotions. You don’t teach them to go and get arrested because somebody said something they disagree with.
Maybe teach them to organize against people like the aggressor, and rally them out of the school. Or teach them to worm the system so that admins will be compelled to get that asshole out of there.
Simply “punching nazis” because you had an emotional reaction only reenforces the asshole’s behavior, and causes unnecessary grief on you.
But yeah, “punch nazis” because “mah emotions”. Real smart. That’ll teach ‘em!
