And why would you do anything like that? To pamper to American counterparts?
if you really are a Euro, you're brainwashed by American identity politics. Too bad they leak over the ocean.
I think you'll find that the Americans don't have the only legacy of slavery to be worried about - they just kept it going longer than most. As a British person, I've got more than enough historical shame about slavery to make me want to avoid those terms.
