We can't do much about political correctness anymore. But other terms, all related to races, popped up during the Trump presidency. The ridiculing of these terms intended to make fun of people doing these things and in the case of antifa, a label intended to make Black Lives Matter and any resistance to white supremacism equally violent to their opponent.
The whole of resisting political correctness has expanded to memes that cover Mr Potatohead, Dr Seuss etc. etc. The right really has no argument against being politically correct, it just became a nudge nudge wink wink word for them.
In the pandemic, the political correctness of wearing masks became a target as well, there just was no catchy term for it yet. "Freedom."
The teaching of our history that includes slavery also has to be white washed according to the right. It is not right for right children in school to feel guilty for slavery and the America of the 1900s up to 1960 when segregation was the rule.
The implication of all this, for Republicans, is that blacks are indeed inferior, and that all foreigners are a lower class of people. "We will take a few geniuses from India for Silicon Valley, but that's it." They can't say these out loud in public or social media, but when they talk to each other, the buzz words help imply the meaning. The Karens of the world can go about their business unchallenged that way.
