I think I can kinda speak about this topic. I am a white male, who I guess you could say is preppy/rich or whatever (even though I'm not rich) and because of a program that I'm in for high school, I attend a high school where minorities are the majority.
Now, most of the people in the program are not minorities (its something like 45% asian, 52% white, 2% black, and 1% hispanic) and the white and asians are totally always getting the "reverse racism" from the majorly black and hispanic school. I mean, its not even jokes, its just plain racism, that if a white person would respond to the black person in kind, they would basically get totally raped.
Now I also live right near to one of the worst malls in the state, and when my brother and I go there, and look in the shoe stores (Champ Sports and Foot Locker and stuff) black and hispanic kids are always like, "Hey, why is whitey here." That just pisses me off, I mean come on now, I have never said anything to you, and you need to say that.
But, to actually respond to the question asked, I am pretty much ok with the white humor, except, when thats the only they've got, it borders, or even crosses the line into racism, and that really pisses me off.
