honestly if we are giong to be accurate about race, i like the terms caucesoid, negroid, mongoloid, australoid, etc...we should stick with that
And if we are talking about a causecoid, we say, he/she is a causecoid from Turkey...etc etc...
None of these subclasses are offensive. Secondly, they are scientific..so if anyone is offended by science, well, they can just go to mars and live over there.
