One of the reasons I'm afraid to ever move away from the area I live in is the relaxed attitude the people here have about race. I have a Chinese friend who says "it's because you're black" anytime the tiniest thing goes wrong around me. In return, I ask him to repeat that in English, 'cause me no speaky Chiney. I knew a white guy I used to jokingly call "cracka ass cracka" everyday at work.
I'd probably look like one of the most hateful and angry black men alive if I used that kind of humor elsewhere.
