The second most racist group I have encountered has been upper middle class white American liberals. in terms of specific racism, the worst behavior spikes come from the women of that group talking to minority women in the working class.

MAYBE that's an upper-class to lower-class female dynamic. IDK.

When I was doing my immigration show, the station's resident hippie used to try to get me to admit my "hate" of Mexicans; I don't know if he really meant what he was saying or whether he was just trying to "catch" me as a racist, but the things he said were so off base from a rational perspective (of course, everything the guy said was moonbattish)...I had to keep laughing at him; I have probably spent more social time with working class Tejanos than I have with upper-class liberals, and my dating pool is primarily Latina
