It shocked me the first time I met a real anti-Semite, in real life, in Tennessee. I've worked in a lot of places all over the world and I've seen plenty of racism. No one else topped that guy in Tennessee. Other places racism was mostly contained to 'they stay over there and we stay over here.' Tons of problems but living together but apart was possible. That doesn't speak to every experience obviously. That old guy in Tennessee wanted another Holocaust, plain and simple. Anywhere else he'd get the shit kicked out of him, there it was tolerated.
Had someone try to sell me on the merits of the Ku Klux Klan while working at a factory in Tennessee, I was a staunch Libertarian at the time so i guess he thought i might bite, he told me how they helped the community out and kept people safe.... the guy was dead fucking serious, and when I asked him about them being racist he just changed the subject... Still feels like a fever dream...
I drove through Alabama once. That was enough. What a shit stain state? Experience the racism there, even if sort of second hand, was surreal. Sucks I know some people that were forced to move there.
