I was dubious when first reading it, as I think PC hype is almost always overblown. Since Fox News, right-wing talk radio and blogs almost universally brand "political correctness" as some sort of "attack" by the liberal elite on aw-shucks folks who were just doing their jobs the way things have always been done, I straight-up view any "PC" charge as lacking in credibility. Think "War on Christmas," and you'll remember what I'm talking about.
No right-wingers seemed interested when Bush protesters were herded into "free speech zones" at UGA, or were denied access to St. Simons Island during the G8 in 2004. I have often argued with conservative friends that most of these "PC" rules are no different from actions taken in small towns across America to keep people like me from bothering the good, church-going baby darlins with heavy metal, rap music and library books like Huckleberry Finn.
As I kept reading this article, however, some of these concerns were addressed:
Because America’s universities tend to tilt left, and because many targets of P.C. censorship are socially conservative, campus censorship has too often come to be understood as a niche issue for the conservative media and blogosphere. This is a bizarre development, not only because free speech was once a central liberal cause but because liberals are by no means immune from campus censorship.
The perception that free speech on campus is primarily a conservative issue ultimately enables campus censors. Free speech zones, for example, are often tiny, out-of-the-way areas where some campuses quarantine protest activities. Obtaining permission to use even these limited spaces often involves waiting periods and registration requirements. In my experience the zones disproportionately affect left-wing protests.
The reason for P.C. censorship often has nothing to do with left or right. Sensitivity is often a cynical excuse to squelch speech that administrators don’t like for purely self-interested reasons.
Free speech still is a liberal cause; I would argue that free speech, respectful discourse, and free inquiries make up one of the central pillars of individual liberty. But anyone can be a bully regardless of political belief; anyone can abuse power once they have some. This is as true on a college campus as it is anywhere else in the world.
