Wikipedia: Political correctness
Political correctness (adjectivally: politically correct), commonly abbreviated to PC,is a term which, in modern usage, is used to describe language, policies, or measures which are intended not to offend or disadvantage any particular group of people in society. In the media, the term is generally used as a pejorative, implying that these policies are excessive.
 
The term had only scattered usage before the early 1990s, usually as an ironic self-description, but entered more mainstream usage in the United States when it was the subject of a series of articles in The New York Times. The phrase was widely used in the debate about Allan Bloom’s 1987 book The Closing of the American Mind, and gained further currency in response to Roger Kimball’s Tenured Radicals (1990), and conservative author Dinesh D’Souza’s 1991 book Illiberal Education, in which he condemned what he saw as liberal efforts to advance self-victimization, multiculturalism through language, affirmative action, and changes to the content of school and university curricula.

, “NRA Presient Heston Backs Arizona SHooting-in-Air Bill,” pg. 2:
Charlton Heston wants politicians to stop being politically correct. The actor, who is president of the National Rifle Association, gave a short speech before Arizona’s House of Representatives in Phoenix before they convened for the start of the 2000 legislative session.
 
“Political correctness is just tyranny with manners,” Heston said Monday. “I wish for you the courage to be unpopular. Popularity is history’s pocket change. Courage is history’s true currency.”
