Probably more like "be wise enough to understand the world and yourself without feeling overwhelmed by it" because almost invariably the reason people have so much venom for the "other" is due to their own insecurities and misconceptions ("if I make you feel bad about yourself and you accept it/don't fight it, I'm better than you and that gives me enough fuel not to collapse"), but I guess 'skill issue' is succint, lol.
