Well, I don't really believe what Trump is doing is either weird or creepy, that is, when you actually analyze what's found a home under Critical Race Theory (CRT) that Trump's opposing.
Indeed, Trump's voiced concerns are concerns shared by a lot of us, a large majority, I would venture.
"White privilege", "White guilt", and "White fragility", to name three, are interrelated theoretical constructs all born out of CRT. These constructs basically say that all White people, due solely to the color of their skin, are: 1) privileged over all other races, 2) all White people know they're privileged, consciously to some degree, at a level that could be at least partially unconscious, and experience guilt about their privilege and how the lack of same privilege experienced by other races has caused those races inequities, and 3) that all White people experience a fragility about their privilege being the founding aspect of their racism which all White people have, racism in their worldview, positions, or advantages, and their fragility makes them defensive about it.
However, there are three very glaring problems today associated with these three interrelated theoretical constructs: 1) they're all blatantly false, 2) these false constructs are being attempted to be brainwashed into the psyches of White people, codependently forced into them in the form of innocent-appearing "inclusion and diversity training" workshops at universities, other institutions, corporations, and even departments of government, and 3) if a White person openly refuses to accept this, in essence, indoctrination, then they are likely to get falsely accused by leftist mobs of being a racist and then "cancel cultured", leftist mob-harassed and fired from their position, experiencing great difficulty in getting rehired.
The fact that these constructs of CRT are all about "what White people all are", "how White people all think", and "how White people all behave", is not only hugely prejudiced, it's all pretty much anti-White racist as well, obviously.
Trump is saying that this form of racism being pushed on us both blatantly and seductively is trying to re-write American history, such as in the CRT-related "1619 Project" that would attempt to rewrite American history with its false narrative and conclude that thus people of color should be allowed segregationist privileges in compensation that other races (specifically Whites) cannot partake of .. and thus it's appropriate that Trump would present his opposition to such segregation and all things CRT at the National Archives where our accurate history documents are stored.
Well, his presentation is working because it falls on very receptive ears, and understandably so.
White people .. well, the large majority of White people, those who don't suffer from situational predisposed codependence and those who don't opportunistically hope to hop a ride on the left wing power train by feigning acceptance .. they don't want to be brainwashed and indoctrinated, and if they don't take this beastly mark they don't want to be "cancel-cultured" and blackballed from work and unable to earn a living.
I mean when you look at it all accurately, the opposition to these three false constructs of CRT are obvious and understandable.
If those who think there's racial inequities to resolve really want to make cooperative progress in ending them, they would do well to drop the CRT false doctrine blaming and find a different approach .. that most would then find worth listening to.
