Those that profit and benefit from racial division (led by politicians) have done a surprisingly successful job bringing racism back, mainly by convincing black people (1) they are perpetual victims and (2) it's white people's fault.
There are not rationale arguments to be made for either of these wrong ideas, but it doesn't matter. I think the survey is about correct; about half of black people have been convinced of these lies. And for a lot of them, it's become a core belief they won't easily let go of.
Unlike the guy in the video, I refuse to write off the other half just because they share a skin color with different people who are racist. I refuse to let anyone sucker me into giving up on 25 million fellow Americans, just because they are black. We cannot let the race baiters win.
Instead I'll pay close attention to people's behavior, and I'll withdraw from those that hate me or wish me harm. This era is going to require caution and keen judgement.
