All joking aside, you can talk to a teacher, your parents can bark at the administration, and all that will happen will be that "oh that pski kid complained about so and so." Unfortunately there isn't a whole lot to do, but know better, and if nothing else see something from another perspective.

I've heard the expression here "War of Northern Aggression." It took me a lot not to smack the professor, but sometimes you just have to sit through it and play the game. It makes you a better person. I'm not even gonna start on the religion teachers here, who ask for your favorite bible verse to open every class. VOMIT.
