You are confusing the teaching of history - which was always done. I learned everything you just listed in school, and I'm old.
CRT is a political movement. It sells the notion that instead of economic classes (classic Marxist thought of the oppressed vs oppressor classes based on economic status), instead of that, they claim western society is made up of racial classes - oppressor (white) and oppressed (dark) -- so that every institution in our country is steeped in racism, and even things that are not racist really are racist because ever system we have is racist. That's what CRT teaches. Or rather, it's a method of teaching - so when we learn of a system of government, we learn that it is racist - "Our Democracy" they say is racist -- and our economic system, capitalism, they say is racist, too. The proponents of CRT say this - and believe it - capitalism is rooted in racism, and is there to benefit the oppressor (white) and harm the oppressed (dark). That stuff is falls. It sells a false narrative on which to place our history, culture, law, government, politics, and economics.
I don't claim the "moral high ground." I don't need a moral high ground to know that CRT is shit.
The problem I have with much of the Left today is that they aren't even concerned with Logic and Reason - and they are decidedly postmodernist in that regard. The Left has adopted the notion that they don't even have to be logical or rational, because like everything else in western society, that's racist and oppressive to require people to be logical and rational. Reason is a western concept, colonialist, and racist.
