I actually kind of agree with Nepenthe there. A lot of progressives have certain ethnic groups that they're allowed to make fun - even going as far as using ethnic slurs, if they're not in the no-no category. I find it hard to believe these people indulge in that sort of stereotyping without harboring some other stereotypes about other groups. They just don't show it. This would all make a lot more sense coming from her if she wasn't insanely racist, though.
