Well, what are the rules of political correctness? Don't the rules vary, depending upon the crowd with which you're running? For example, what Fox News would consider politically correct would be very different from what a normal news network would consider politically correct. And, the term often ends up being used in an accusatory manner from one party to another. Typically, someone like Rush Limbaugh will denigrate another point of view by labeling it as "politically correct", while he maintains his own strong opinions about what is, in his mind, "politically correct", but without calling it that.
