Eh, I am not terribly pissed. The stereotypes are more or less all internal stereotypes. If you are not okay with the gay, “bear” and “twink” probably means nothing to you. Hell, even if you are okay with the gay, unless you are gay or actively have gay friends and live in a city bug enough to have a gay community, most of those stereotypes are probably borderline meaningless.
Chris Rock poking fun at black stereotypes is okay. It is done with the acknowledgement that these are stereotypes. It is however very much not okay for my racist brother in law to spew black stereotypes at me. I guess my point is that context matters.
