But that's the point... a University should be a place for open discussion of ideas. If you do not expose students to the entire specturm of ideas how are you going to teach them to think for themselves. It reminds me of when I was a child and my father, a college professor, use to be angry that communist ideology could not be discussed in many classes because it was considered a diseased idea that would corrupt minds. Ideas don't corrupt minds... minds corrupt reality (or something like that... #-o )
