You're right but the example you gave seems to illustrate a different effect that's almost opposite — let me explain.
The phrase "politically correct" is language which meant something very specific, that was then hijacked by the far-right into the culture war where its meaning could be hollowed out/watered down to just mean basically "polite", then used interchangeably in a motte-and-bailey style between the two meanings whenever useful, basically a weaponized fallacy designed to scare and confuse people — and you know that's exactly what it's doing by because no right-winger can define what this boogeyman really means. This has been done before with things like: Critical Race Theory, DEI, cancel culture, woke, cultural Marxism, cultural bolshevism/judeo bolshevism (if you go back far enough), "Great Replacement", "illegals", the list goes on.
I get what you mean. You're saying we're sliding towards something that brings back political correctness in its original definition, and I agree with you.
This resonates a lot. I'd argue we're already there. All this talk of "meritocracy" (fallaciously opposed to "DEI"), the prosperity gospel (that one's even older), it's all been promoting this idea of worthiness determined by net worth. Totalitarianism needs a socially accepted might-makes-right narrative wherever it can find it, then that can be the foundation for the fascist dogma/cult that will justify the regime's existence and legitimize its disregard for human life. Bonus points if you can make that might-makes-right narrative sound righteous (e.g. "merit" determines that you "deserve" your wealth, when really it's a circular argument: merit is never questioned for those who have the wealth, it's always assumed because how else could they have made that much money!).
