Check out this story– some kids at a school promoted one of their friends for the “African-American of the Year” award, and were disciplined for it. The reason? The friend was white.
But he was from South Africa, immigrating 6 years ago.
So we can’t say black, we have to say African American, but they don’t mean African American, they mean black.
Kudos to the Volokh Conspiracy for the link.
