Political correctness is probably the single most important reason Donald Trump is the president of the United States and the GOP controls most of Washington. They controlled the House of Representatives until 2018, but lost it after failing to deliver on their promises.
The only thing it took for Donald Trump to walk to the Republican nomination was that he cleverly refused to play by that game. He was deliberately outrageous. The populist swath of the electorate is so tired of political correctness that it elected a moron as president to be relieved from it.
Political correctness is a MORAL SYSTEM. It is a moral system that atheists and secular people have latched onto since they gave up on Christianity. The SJW is like a fundamentalist, extremist or a fanatic who takes this moral system to its logical conclusion. It has become their identity in life. It is why they take to the streets to fight with populist identitarians.
Elizabeth Warren is how they sound and look to everyone else in America. It is why Sean Hannity will not shut up about Alexandria Ocasio-Cortez. It is why the GOP latched on to Antifa as their boogeyman in the last election cycle to remind wavering voters how much they hated those people. No one wants to be ruled by these miserable people with their witch hunts and Inquistions.
If you dissolve political correctness, you will find that a lot of warring tribes agree on major issues. The populists and progressives agree on health care, student loans, universal basic income, infrastructure and a lot of other issues which could be tackled. Political correctness is why they fight over purely symbolic things like Confederate monuments. Living under it can drive people literally insane too like we saw in New Zealand and Pittsburgh.
Politically speaking, the people who benefit the most from political correctness are mainstream conservatives. Millions of moderate White voters supported Donald Trump and the GOP because the alternative was, well, living under what is in essence woke sharia.
Note: Political correctness should be recognized as a religion. The way you defuse religious conflict between European Christians and woke progressives is though religious tolerance. SJWs need to be told to settle down and stop trying to destroy the world around them in order to force their confession on everyone else.
