In case you're wondering why there's a push for critical race theory (which critics tend to know almost nothing about), take a look at this piece about a Fox "News" pundit equating the genocide of Native Americans and the forcible seizure of their lands with responding to the attack on Pearl Harbor.
Since this land was "settled" (conquered) by Europeans, white supremacy is the dominant mindset. As we can see above, this fact is present, not just past.
It's worth noting that conservatives' rejection of the legitimacy of our elections began when a black president was a elected, pause when a white supremacist president was elected and resumed when a vice-president of color was elected.
White supremacy requires insisting that America is perfect... other than perhaps the fact that it allows liberals.
The Founding Fathers of this nation knew very well this was not so. The Constitution they wrote tried to form not a perfect union but a "more perfect" one. That's why they provided for an amendment process.
Serious adults know that you cannot improve unless you recognize your flaws. It's time many Americans became less like insecure little children and more like serious adults. It's the only one to move this country forward. It's always the only way to move forward.
Update: I was not surprised to learn that the hysteria over Critical Race Theory was carefully manufactured and well-funded by elites seeking to divide us.
