"The guy is a freaking art teacher. He has another agenda and he's showing who he is. He does not belong in a classroom with children."
If he doesn't want to reconsider his position then he will have to suffer the consequences.
If he is already tenured it will be very difficult to get rid of him.
You don't have much experience with art teachers do you?
Apparently not!!! I don't remember going to art class and being shown movies about social issues. I remember alot of paper mache and acrylic paint!!! :)
