If the people who were attempting to ban "critical race theory" could define it precisely, and ban it equally precisely, I would not have an issue.

That it is banned in public schools is proof that they do not and cannot define it. CRT is a Graduate-level subject that had no allocated curriculum in elementary or high schools.

Rather, it's being used as a dog whistle for all debate regarding privilege, SYSTEMIC racism, the acknowledgement of US history as racist, or work still to be done today.

The bans of "critical race theory" are not actually banning https://en.wikipedia.org/wiki/Critical_race_theory but openly suppressing discussion of civil rights and racism.
