From Merriam Webster's Top Ten List, we have the following tidbit on "Politically Correct
#5: Politically Correct
It so happens that the Left invented this phrase: it entered Communist lingo in the 1930s to praise loyalty to the party line.
But eventually politically correct turned against them.
By the 90s, it was used mainly by the Right – as a kind of battle cry of the Culture Wars.
Here's President George H. W. Bush, in a 1991 commencement speech at the University of Michigan:
"The notion of political correctness has ignited controversy across the land. And although the movement arises from the laudable desire to sweep away the debris of racism and sexism and hatred, it replaces old prejudice with new ones. It declares certain topics off-limits, certain expression off-limits, even certain gestures off-limits."
Political correctness has its roots in COMMUNISM.
Say what you mean; if some Leftist whiner pansy is offended by you for speaking clearly then they need to grow up and grow a thicker skin. Don't let them silence you for not being "sensitive". It is they who are insensitive by trying to force you to speak like them.
