Okay, the Wikipedia article’s treatment of critical race theory is clear as mud, — but it’s worth noting that nowhere in there is the notion that being white is bad.
The theory calls out white supremacy, but you can be white without being a white supremacist. Obviously.
The theory discusses how the white supremacy that was rampant across society in former years (slavery, Jim Crow, etc.) continues to have ripple effects in our laws and culture today, but that still doesn’t equate to white being bad. There were then, and are now, white people who work to combat racism and remove legal obstacles to racial equity. Abraham Lincoln was one of those people. So, in their own way, was every white soldier who fought on the side of the Union, even if they weren’t aware at the time what their victory might mean in terms of the constitutional amendments that came after the Civil War.
Your strawman simplification compresses way too much.
White people are a valid part of our society and always will be. CRT as I understand it concerns itself with the daunting task of making sure everyone is on an equal footing.
