Dressing well, being polite, and liking individualism is apparently white supremacy, along with almost literally everything else. Mozart is racist, cars are racist, milk is racist, education is racist, smiling is SUPER racist.
It's not about the supremacy, it's about the culture. Lefties hate western culture, so they mask their own racism for white people by calling it "white supremacy".
I don't know who needed to hear this, but it just clicked for me all of a sudden: replace "white supremacy" with "white culture" and you lift the mask.
You need to understand it isn't specifically about white people. They have to tear down the existing culture/system to institute the Marxist paradise/attain the power they envision (it's always the elite that initiate the Marxist revolution). The same pattern we are seeing now, already played out in China with Mao, Russia with Lenin/Stalin, Cambodia with the Khmer Rouge, and on and on. The same rhetoric was used in all of them. Institute gun control (this may occur at a later point in the order), demonize a group, paint them as "privileged", blame them for all of the problems, dehumanize them, institute uneven application of laws, have your "brown shirts" actively attack/kill those scapegoated (with military weapons supplied by the government) , eventually outright systemic elimination of the opposition. It is always the Marxists genociding the cultural conservatives. If you think it can't happen here, you need to wake up. Never give up your guns. It is better to die on your feet taking some of them with you, than to not fight at all and end up shot in the back of your head. https://metallicman.com/laoban4site/what-the-progressive-liberals-have-in-store-for-conservatives/
In the 1920s, American Communists called what we call "white supremacy" "white chauvinism". That was their first word for it. Read the book of ex-Communist Bella Dodd, "School of Darkness". It was her job in the 1920s and 30s to seed the Teacher's Unions with Communists. That crap is paying dividends a hundred years later.
All of the words, slogans and concepts of Marxists in 1921 are now pervading academia in 2021.
Conservatives were complacent and snoozed as all their institutions were quietly being taken over.
