I'm an African American, I lived in a very rural area of my state for over 10 years, there were no bus routes, most people lived in trailers, when it snowed it often wasn't maintained very well, the cinders that they(road crew) threw down on dirt roads (yes dirt roads) weren't adequate for road safety maintenance. Chains like Walmart also took away business from small business owners, and stores that were in families for generations had to close down. I more than a lot of other people know about rural poverty.
However there was a lot of racism, a lot of damaging racism, with effects that I still deal with today. So to say that rural whites don't know any better or they don't have the education, that's why they're racist, it's cop-out, and it essentially excuses how they treat low income Black and other PoC who live in those areas who in addition to being poor, face racial discrimination as well.
While I was in HS, I really really did try to calmly explain to racists why saying the n word was offensive or touching my hair without permission was wrong or why asking me, one Black person to give an opinion on an entire race is unfair...but most...didn't care, they didn't listen...and eventually I faced racial harassment so bad that I had to leave school.
Rural whites certainly know that racism is wrong...there's no question about that. I think you can talk about how democrats could cater to them better. How white liberals treat them, but no burden should be put on Black and other PoC to educate people like that. There's no both sides on that angle, historically and currently Black people have never treated white people like they have treated us...so to say both sides...that's a false equivalency.
I understand the poverty, but it does not excuse the racism and I do not have empathy for active racists who vote based on hate rather than policies that will help everyone.
