Arguing about the meaning of "PC" is as irrelevant as arguing that "gay means happy". Brass tacs time: "PC" as it stands today means the support of a diverse society by means of suppressing diverse opinions. Wikipedia describes it as "a term denoting language, ideas, policies, and behavior seen as seeking to minimize social offense in gender, racial, cultural, sexual orientation, handicap, and age-related contexts" and dictionary.com states that it is "marked by or adhering to a typically progressive orthodoxy on issues involving esp. race, gender, sexual affinity, or ecology." So no more confusion over what it actually means. No matter what source you aim for, all the official and academic interpretations clearly state that PC is a method of social engineering based purely on the concept of forcing public opinion into a single direction. It is probably a well-meaning idea at heart but its application has been so utterly corrupt and disgracefully managed that it has become one of the darkest forces in our culture.
