Oh I 100% agree that the people complaining about 'censorship' from private platforms need to chill. The only reason those platforms matter is because they earned that position in the market, and they can do whatever they want. The only way I'd really except something from that rule is if a private platform discriminated when acting in a government capacity (say, contracting for a Department of the Federal Government), but to my knowledge that has not happened.
The issue with CRT is it doesn't just acknowledge, "Hey, some of you are better off than others, it's the world into which we were born." It actively seeks to shame and degrade those born with more. That is discrimination based off intrinsic characteristics, not personal merit or actions, and that is wrong. There's a difference between saying, "Hey man, at least be aware that some people are way worse off than you." and "Listen bud, you should be ashamed that you were born white and rich." I didn't choose to be born white and in a middle-class family, so why should I be judged for it? Were I to go about bragging about such a status and how it makes me superior to anyone, not just blacks, born with less because of historical discrimination then yes!! Lambaste me because I am being a serious tool!
Just my $0.02 on the matter, anyhow.
