Yes, but they think they are, and that is tactical shortcoming. By being over-confident they are easier to attack given thought and patience. anyone that desructive is, well, destructive and and kind of aggression can be redirected by a trained and paient adversary. Don't get in a shouting battle with them, that is their stong point. Club them in the head as they yell in public.
