Mind Your Ps and Cs

"In the late ’70s, 'politically correct,' 'PC' for short, entered the public lexicon. Folks on the left used the term to dismiss views that were seen as too rigid and, also, to poke fun at themselves for the immense care they took to neither say nor do anything that might offend the political sensibilities of others. 'You are so PC,' one would say with a smile. In the ’80s, the right, taking the words at face value, latched on to the term and used it to deride leftish voices. Beleaguered progressives, ever earnest, then defended political correctness as a worthy concept, thus validating conservatives’ derision. Today, on both the left and the right, being PC is no laughing matter; three decades of culture wars have generated a bewildering thicket of terminology."
