Why should it have to be? Not only do I not see that asserted in RDKirk's post, more to the point I don't see that asserted by people involved in education like my own bosses, who actively push DEI initiatives and CRT by other names.
Have you never heard the advice that one ought not attribute to malice that which can be attributed to stupidity? This works kind of like that, in that it functions as it does because the administrative class believes they are doing something good for mankind, and having enough people on the same page about that is what creates the 'conspiracy' (to use your word) whereby they then deny any evidence that their crusade is potentially or actually harmful. It's not a conspiracy -- it's scuttling evidence that may cause a decrease in acceptance of the rightness of the goal for the good of those they seek to help. They're 'stupid' when it comes to recognizing the unintended consequences of their social engineering projects (whether that's CRT, AI, or anything else), not malicious. (It's also paternalistic as all get out, which is probably another reason why parents are often suspicious of it, but that's probably a conversation for a different thread.)
