There was a time when political correctness was nothing more than a rule protecting certain students from insults on college campuses. Since a majority of tenured professors were the guys who got beat up a lot in eighth grade, it was important for them to create a learning environment where the dorkiest kid on campus could walk to class without hearing the football players snicker at him from behind the bushes.

Since it was just college, nobody really cared too much about the censorship, but now something really scary is going on. The President of the United States belongs to a protected demographic and political correctness has made jokes about him verboten.
