Show passion, but then live with the consequences.
When you get pulled over by the police, they have 100% power. You can't beat them. If you argue/curse at them, they'll still win, but possibly make it 10 times worse for you. Not the best example, but that's how umps are. They have all the authority in baseball and you can't beat them. So curse at them, and live with the punishment. They are wrong more often than not, but what the hell are you going to do to officials who are bullet proof? You can't fight them.
