Lol then the answer is simple. As always, the more PC they try to become the more slang the youth will invent. Lol it's almost like an arms race!
That's the general idea, but it's even more nefarious than that.
You can control social conversation by controlling the words.
If there is a word which has no real corollary, like "racism", and then you redefining it;
you can suddenly no longer have a conversation about racism in a traditional way,
because you NO LONGER HAVE A WORD FOR that traditional meaning.
If you change the meaning of words, then you can no longer talk about the things you used to talk about...
because there aren't words for that.
These are very clever things done by very clever people... with intentionality and planning.
These aren't accidents.
It is a very authoritarian way to control people.
