They're are a couple of Civil War bloggers who like to poo-poo the notion of political correctness (most likely because they are so PC themselves), but their denials just make them look silly. I think they're so embedded in the PC culture, they're unaware or, maybe, too much of a coward to speak the truth. Here's what Jerry Seinfield has to say about the subject. His (and others as well) advice? If you have a sense of humor (and, I would add, common sense), you might want to avoid college campuses.
I originally embedded the audio/video, but the "auto play" is annoying, so here's the link for Seinfield's comments.
