Thankfully, I went to a relatively conservative university where liberal PC rubbish was minimal. Then I went to a law school in the northeast where liberal orthodoxy was preposterous (one comment on one of my papers = for using the generic "he", the prof. told me "Don't use offensive language!"). I bugged out of there to a more moderate place for the remainder of law school that, despite a fairly liberal faculty and student body, was relaxed and relatively tolerant of all viewpoints. So I've avoided some of the worst professorial excess.
Today, John Tierney writes on a study of the political affiliations of the professoriat (link in title); and Stanley Kurtz notes this study in The Corner. Results? About what I'd expect.
