There was a movie about this back in 2004, no theaters here showed it, it wasn't available to rent anywhere. I put in a request at Netflex and they did get it a few months later. It is a highly rated beautiful movie about a tough subject. Maybe you should find it and ask the teacher to show it in class to raise awareness of the oblivious moron in your class.

I would have been on the floor with laughter too, what a moron. He might have thought he was being a wiseass but all he did was show his ignorance.
