We used to have "diversity training" once or twice a year at work. A lot of it sounded pretty similar to this stuff, or what I understand CRT to comprise in some cases. Now, we were adults and it was a go through the motions kind of deal. We did have one session with the technicians attending where it got out of hand because the black technicians told the black "moderator" he was full of S. It got so bad the moderator called our director, who called me to come with him to find out what was happening.
Basically, the moderator had presented to everyone the story that all the whites there were racist and they took it seriously and got unhappy, it really was no big deal, just get through it and go back to work, but some of the technicians took umbrage at the insinuations.
My technicians filled me in later on what happened, they thought it rather amusing. The staff had the same deal later but with a different moderator who was, well, coached beforehand. We treated it as a ticket to punch, be quiet, nod, get it over, and go home early that day.
It it's teaching history warts and all, fine with me, but if the idea is to make white folks feel bad about it by slanting the story so much that it is presented as THEIR fault, I can't sign on. I imagine there are many variations called "CRT" that include a lot of different kinds of things.
Just teach history.
