Well, I say more power to the instructor, he was within his rights, his opinion counts too.
I wish I could say that I would have done the same thing but I don't have the gonads he does. I would have just figured a few of these guys had voted for obamma and gone on with it, and wondered who it was.
As for him being fired, hey he put in his time and should be thanked. He is smart enough to figure out that those few obamma voters will eventually turn this country into ........ mess.
