History of PC
Political Correctness started in a think tank in Germany in 1923. It was going to be called The Institute of Marxism but in order to hide its Marxist roots it became known as The Institute of Social Research. The purpose was to find a solution to the biggest problem facing the implementers of communism in Russia. Why wasn't communism spreading? Because Western Civilization was in its way with its belief in the individual and that an individual could develop valid ideas.
At the root of communism was the theory that all valid ideas come from the effect of the social group of the masses. The individual is nothing.
And they believed that the only way for communism to advance was to help Western Civilization to destroy itself by undermining its foundations by chipping away at the rights of those annoying individuals. One way to do that? Change their speech and thought patterns by spreading the idea that vocalising your beliefs is disrespectful to others and must be avoided to make up for past inequities and injustices. Then use this to stifle any discussion which might show up the lack of common sense in their ideology. And call it something that sounds positive: "Political Correctness."
That is how Political Correctness came about and why it is the tool of the far left in politics. When Hitler took over Germany in 1933, the Institute moved to the USA (as most of the thinkers were Jewish).
