Excellent post. The true purpose of PC is psychological dominance, and it works. 100 million dead in communist countries, as well as Hillary’s knee jerk supporters, prove that. PC is as evil as it gets, and has caused more death than any other device.
Rewrite history, change the meaning of words, outlaw the use of certain words, we are now into 1984 territory.
PC = Partyline = Groupthink
