I don’t see anyone doing that. That said, Jim Crow and the KKK, and the institutional racism that grew from them were not driven by Asians and Latinos. If we want to be honest, we need to acknowledge that whites in the US certainly carry the heaviest burden of culpability.

No he will not. Answering your questions is too much to ask of someone who’s digital footprint illustrates in his own navel-gazing victim mentality.

Who else is responsible for the significant racial imbalances (in housing, employment, heath care, the justice system, etc) in the US today?

While whites are NOT the only ones who can be racist, they are the ones who set up (and maintained) the power structures in the US for centuries. Although, the overtly racist laws, policies have been rescinded, the effects of those laws are influencing policies and attitudes in the US today. And if you would bother to educate your self about what CRT is (and what it actually teaches) rather than just listening to the propaganda against it, you might see a bit farther.

Racism is a serious and complex problem, and faulting only white Europeans for it, is very simplistic as far as I can see.

If racism is a serious problem sometimes as you indicate, it is a serious problem.
