Many people don't know. They also don't know about the emergence of private schools i.e. segregation academies, that arose solely because they could exclude Black students. Or that so many white evangelical grievances are rooted in racism. https://twitter.com/amywestervelt/status/1347384335767199745
This is rarely taught in schools. School boards like Texas' deliberately minimize this country's racist past in the curriculum. My AP US history class made it to WW2. We learned about post 1942 in bulleted form and stopped @ Kennedy. I still got a 4 out of 5 on the test though.
The typical person reads in the US reads 4 books a year. Unless they seek out this history they aren't going to learn that the erosion of so many public services from community pools to public schools, is b/c post civil rights, white ppl would have to share them with Black ppl.
Shit, towns filled their pools with concrete rather than share them with Black people. You can absolutely look at the rise of neoliberal economics and the push for privatization as a way of segregation by another name https://www.businessinsider.com/roosevelt-institute-director-how-neoliberalism-sustains-racist-systems-2020-7
Anyway here's a 2012 article on segregation academies persistence https://www.theatlantic.com/national/archive/2012/12/in-southern-towns-segregation-academies-are-still-going-strong/266207/
Oh one other thing! I didn't grow up in Texas I grew up in NYC. But what Texas decides have implications for the rest of us. This is from 2012 but afaik still true https://www.nybooks.com/articles/2012/06/21/how-texas-inflicts-bad-textbooks-on-us/
