why, mofh? "Black" was the nomenclature, chosen by blacks, with which to repectfully refer to the race.

And American Blacks -- as a race -- are not "Arican Americans". Certainly they are not in the context of this thread. For one thing, it's not at all descriptive. It doesn't distinguish Canada from USA from Mexico, or, for that matter, does it even distinguish North from Central from South America. And that's without even mentioning how diverse Africa is (even moreso than N. America).
