This is wrong. CRT is basically repackaged class war, and Marxism.
I was born and lived under communism, and a lot of the means CRT is peddled, feels eerily similar to communist/socialist propaganda and perpetual class warfare. Because you have to have some kind of eternal enemy in order to prop up the ideology, even if it is a failed/bankrupt one to the core.

You didn't disagree with me. By repackaging something it opposes it. That's called the narcissism of small differences - CRT is a liberal thing and nobody hates liberals more than leftists.
Anyway, you don't seem to be talking about critical race theory (something taught in graduate schools) but instead critical race theory (a collection of unrelated or made up things Fox News has decided to complain about this year.)
The connections between most of these are just that different French people wrote about some of them at the same time. e.g. Marxism and postmodernism are also opposed to each other.
Corporate trainings of course also don't contain hardcore theories, because the point is to be inoffensive and prevent lawsuits. Ibram Kendi or Robin DiAngelo might show up and do a talk (these people also don't exactly agree) but the actual result is that people are going to start saying "allowlist" instead of "whitelist".
None of the analysis is falsifiable so it is closer to religion than anything else. Based on the above lens these ideologies deconstruct things like laws and structures, or science and this is how you end up with racist math, racist knitting, racist birds... racist everything.
