William Voegli claims that the phrase 'political correctness' first entered the American vocabulary in 1991. I don't know about that, but I do know that the concept is much older: PC derives from the CP, as I explain in Dorothy Healey on Political Correctness.
I now refer you to what Bill Whittle has to say about the leftist narrative and political correctness. (HT: Monterey Tom)
Whittle refers to a man I blogged about on 30 August 2009:
The Gun-Totin' Obama Protester Was Black!
If a black man exercises his Second Amendment rights, is he really black? For liberals, the answer, apparently, is in the negative. For them, apparently, the only real black is a liberal black. Take a gander at this video clip. You will see an Obama protester with a semi-automatic rifle slung over his shoulder, a pistol on his hip, and an ammo mag in his pocket. But the shot has been edited so that we cannot see that he is black. And you liberals have the chutzpah to tell me that the MSM does not tilt to the Left? To depict the man's color would not fit in with the leftist party line that opposition to Obama's policies has its origin in racism. Apparently, a black man who does not fit the leftist 'narrative' is not black, but a 'traitor to his race.' And the same goes, mutatis mutandis, for women who do not toe the party line.
In this clip you can see that the man is indeed black.
Here are two points that need to be made again and again in opposition to the willful moral and intellectual obtuseness of liberals and leftists.
1. Dissent is not hate. To dissent from a person's ideas and policies is not to hate the person.
2. As a corollary to #1, to dissent from the ideas and policies of a black man is not to hate the man. A fortiori, it is not to hate the man because he is black.
