Something I have learned from my partners is that white men gleefully assume that other white men are just as disgustingly racist as they are simply because they are white men.
The things that customers say to my partner with the full confidence that they must be speaking to a fellow bigot are disgusting.
Like, white women on balance are every bit as racist, but this good old boys club attitude, this belief that every other white man is in this with them, is something really special.
