Grew up in Montgomery public school that was right around 50/50 and I lived in a pretty middle class neighborhood that was probably 70% white. Direct neighbor on one side was black family for 10+ years when I was a kid. Had a kid one year younger than me and we played almost everyday.

I played on sports teams that were majority black and many of those guys from HS are family friends to this day even though I moved from hometown.

Roommate and one of best friends in college was black and he was also a groomsman in my wedding.

2 of the 5 direct bosses I’ve had in my career post school were black.

Like the OP said my life has been spent in a truly racially mixed environment with nothing but steady progress towards race becoming all but a non-issue in the real world. Now I’m seeing my elementary school kids and their friends being forced what I believe to be a false narrative about some overwhelming current systemic racism problem in this county and the inherent racism in being a white person. It’s infuriating and sad to see our adult teachers, community leaders and politicians basically trying to revive the race problems that were so prevalent in this country and destroy the progress that has been made. I was confident my kids generation would grow up in an era that MLK had dreamed about and that we were finally there as a country. But if the real everyday Americans don’t stand up and push back against this false narrative going on our kids are going to indoctrinated to think that America and white people are irredeemably racist and then what?

And this is mostly spurred by isolated incidents of mostly career criminals playing with fire over and over and getting killed by the police. Some of those incidents were wrong, some weren’t. In the scale of policing they are extremely rare regardless. When it’s wrong we prosecute and convict like we should. Why are we tearing our country apart over this?
