"I don't think that the law enforcement system is systemically racist"
- William Barr....
Looks like not everyone is aware.
Barr is, of course, a worthless person to poke at when it comes to that, because it's fairly certain that he knows about the racism, approves of it, and is willing to lie to defend it. Much like the rest of the good ol' boys club that is the power in and behind the Republican Party.
There is widespread ignorance regarding racial issues... and it starts at the top, with Stubby McBonespurs.
I disagree with it starting at the top. I've poked at this before, though, but... I've actually been a little shocked at my mother (a wonderful woman, but ignorant on the issue, like so many other white people that have mostly been surrounded almost exclusively by white people for their entire lives) slowly starting to comprehend that racism hasn't actually vanished and being shocked and horrified when confronted with evidence. In her case, if I understand it correctly, that journey started with a speaker at church who detailed some of the great injustice visited upon him - the writer of
Just Mercy, I think?
Ignorance abounds, yes, much as it seems that there's increasing interest from people to learn.
As for the sports related protests, regardless, I neither support nor oppose them, directly. Probably because I think that watching sports is boring.

I do, however, think that the objections that I've heard to various protests have largely been unconvincing to me from an objective standpoint. At least there are a couple valid objections that can be made to athletes going on strike, though. The objections to kneeling seemed to all be utterly inane.
