Thread drift alert (but I didn't start it): Caucasians? I doubt if any Caucasians made to America until late in the 19th century.
Yeah, I know this weird term is still used in America to mean people whose ancestors mostly came from Europe. But it reeks of 19th century pseudo-science, when they were busy inventing racial classifications as a way of underpinning racist policies.
I doubt if many black Americans would appreciate having the generic term "Ethiopians" pinned on them - and if anyone ever refers to me as a Caucasian that's how I feel. (And I imagine people hailing from Ethiopia and the Caucasus would resent this barbarism even more.)
