I was wondering if George had to check dude on his racism one time or something, or if he just knew not to fuck with George because he knew he wasn't having that shit.
Add that to the fact that George had a white woman and had appeared in pr0n, you got the recipe for white male supremacist rage. If Chauvin knew solely these 2 things, he hated George with everything inside of him even if he knew nothing else about him.
