Black Republicans.

2. It isn't limited to African-Americans.

Gay republicans (the Log Cabin Republicans) and Jewish republicans get the same treatment. To a lesser extent, I have similar attacks on Latinos, and even more rarely, women, who are republicans.

What I find interesting is your comment, "We are supposed to be unquestioning Democrats, even when Democrat social values conflict with our own." Which "Democrat" social values conflict with African-Americans?

The attacks on minorities, especially AA, gay, and Jewish ones, for being republicans, IMO, demonstrates a need by some in the majority (of any majority) for minorities to be of a 'hive mind'. We are supposed to stay with acceptable parameters and when members of our community dare to step out, then the entire group is suspect. Of the three groups primarily targeted, all three are almost exclusively democratic and have shown this in election after election, except those groups, especially gays and Jews, are often singled out for "costing us the election" or "not being out in force enough." Now, we are seeing the concerns of AA folk being labeled "wedge issues", and as someone who has been to this rodeo, this is just the beginning!
