I'm of black descent myself and I agree. As a black conservative, you wouldn't believe the times I've gotten flack from other black people for my political choices, not minding if white actors voice black cartoon characters (while nobody complains when the reverse happens), liking white women (I've actually been called brainwashed for doing so), and even telling black folktales (i.e. the Uncle Remus stories, never mind that they existed long before Song of the South). And then there's the times I've had it pushed into my head that conservatives (who are apparently all white despite evidence to the contrary) are trying to bring back slavery. Most of the racism I've experienced has been not from conservative Western Europeans, but from Eastern Europeans, liberal white people, and other nonwhites.
Speaking as someone who fits both criteria, this is true. I've also had people have the gall to correct me with "people of color" instead of "colored people" (never mind that there's practically no difference between the two terms, and the fact that I'm a colored person (with some white ancestry)), or call me racist for not liking Michael Jackson's music (never mind that one of my colored heritages is black, and you can dislike someone or something without their ethnicity being a factor).
