Political correctness was developed by the Communists/Progressives to control the narrative for obvious reasons.
It has worked remarkably well.
It only works because they were able to get control of all curricula in 1930s and all publishing companies so they could warp the little children and flip their worldview from Christianity to Materialism (humanism). By the 60s, they had the Bible and all worldview which created the Constitution erased in the schools and they started with the Neo-Marxist, Neo-Freudian brainwashing of very little children to destroy their natural desires and understanding of Truth (God)-—with the help of the sodomites in Hollywood (the ones raping all the little boys like Cory Feldman).
This Jekyll Island plan was designed to flip 2000 years of worldview back to the ignorant serf-minds of slaves (pre-Christian)-—to remove all the philosophy and genius which created the US Constitution and Rule of Law-—and they vilify ALL the white males who created the Age of Reason and Modern Science, so they could discredit their worldview—and ERASE IT from the future minds-—to create little non-thinking “bots” for the evil elite sodomites and their NWO of total slavery of the masses.
