Brian20o2, your situation is such that you either have to do something to make things better for you, or you decide to accept those guys and just not be bothered by them. Since you're clearly bothered, you will have to do something. Specifically what I wouldn't know. You've got to decide on the best course of action. However, things could either go your way or go to hell. If hell is the destination, then you just have to quit that class for your own peace of mind.
So, if you don't want to do anything about those guys, you better run. Otherwise, try harder to accept others for who they are.
