I remember getting into a discussion with an Indiana University American lit professor about Ayn Rand, and being insulted in the process. She was a Leftist, of course, who, in addition to hating Ayn Rand, believed that American business was evil for failing to produce the same lines of shoes for her freakishly small feet.* My grade, which prior to this discussion had been a high A, suddenly dropped to a low C. Without a single paper having been submitted. Something about an "entire body of work."
That was 20 years ago. I can only imagine what the environment is like today, after eight years of Clinton and almost eight years of Bush. If you want to know more, sign up for a local screening here. I did.
Edit: I forgot to mention: this is a link to Indoctrinate U., which looks like a fascinating documentary on the topic of higher education anti-dissent.
*They really were freakishly small. I'd say she was probably somewhere in the top one percentile of people with very small feet, meaning that any shoe company that tooled their factories to make a full line of shoes for her would soon go out of business. Such crass business concerns were beneath her, though, because she was talking about her right to whatever shoes she wanted!
