Yes, it is. The question is why 56 years after the passage of the Civil Rights Act, we can't shake off the affliction of racism. It still consumes all of us, on the right and the left. It is frustrating.
There are those whose power comes from promoting the idea of rampant racism.
There are a lot of people who find racism a convenient excuse and avoid addressing the real, much harder issues.
Also, race is an easy proxy for lots of other things to continue the economic divides in this power. This requires a couple of things that you don't like to admit (which is ironic, considering your post here, but you know, par for the course).
First, it requires racism to be real and fairly widespread. This is clear to anyone with eyes to see.
Second, it requires plenty of demagogues to use race or racial dogwhistles to constantly blame others for problems that those in power are usually responsible for causing.
Simple, widespread, and trivially true.
