Yes, we know. We have been pointing that out. But that leaves this kind of analysis, examples of which one could lift from essentially the entire faction that regards "PC" as being a legitimate category of bad thing, hopelessly muddled, and biased in its confusion. Because if you make a big deal out of "politically correct" only as applied to what you have been engineered and manipulated into regarding as leftwing interference with thought and language, you are complicit in the enforcement of the rightwing stuff. You are cooperating with and abetting the New World Order thought control, almost all of which is rightwing in origin. You have been led to see and discuss only what you have a name for. The left is not the powerful, media owning, well-financed faction in the US. Most of the actual thought control via language control, most of the cunning manipulations of the social engineers bringing in their idea of a New World Order (HW Bush's term during his campaign, no kidding - we can only hope the WWII veteran forgot where the term came from (http://ww2today.com/30th-january-1941-hitlers-new-world-order): ), is the doing of the authoritarian corporate rightwing media professionals. The likes of Lee Atwater, Karl Rove, Frank Luntz, Rush Limbaugh, Newt Gingrich, the entire frontline and writing staff at Fox News, have been dominating the US public discourse with the rightwing "politically correct" manipulations. And the people complaining about lefty "political correct" bad stuff? They're correct in a small sense, of course - Carlin is perceptive, insightful - but by missing the larger picture, they get the entire situation completely wrong. And that is to the benefit of those who benefit from an inculcated inability to reason - who by some chance are the same people financing the media so dominated.
