When I lived in LA, the Mexicans told the best Mexican jokes, and the blacks told the best black jokes. It was fun. Nothing sad about it.
I guess I think it’s sad because to the best of my knowledge white people don’t tell white jokes. Our culture is something we’re proud of. At least, it is for me. The only exception I can think of is specific nationality jokes, like the English used to tell about the Irish, or those old Polish jokes left over from WWII.
