Is "race" (and its manifestations) is a protected class? I'm not sure what the law says. If so technically you're not supposed to use it, because the 14th amendment (which is what AA is based on) mandates "equal protection." Reverse discrimination isn't equal protection.
That said, racial politics in the US are all weird. First there was no such thing as race, then suddenly everyone was using race for everything, and now only white people can't use racial terms. WTF?
As a POC, I'm always amazed at how well advocates manipulate everyone to get what they want. Liberal white people are ridiculously easy to guilt trip, and they keep falling for the same old shit time after time. It's pathetic.
