BUT White directly means Caucasian. Black and Asian for Negroid and Mongoloid, not so much.
Also, why does Caucasian keep its root name but Black and Asian don't?
I'm not exactly sure what you mean anymore.
White may always or just about always mean caucasian, but caucasian does not always mean white. Latinos, for example, are caucasian but people don't call them white.
Black doesn't always mean negroid but it
usually does. Rarely will someone call an Indian "black". They usually just say Indian, or middle-eastern.
Again, I don't think anyone's going to stop you from using mongoloid or some variation thereof. I could be wrong.
The way I see it these are the common racial distinctions in everyday language:
- White
- Latino
- Black
- Middle-eastern
- Asian
That gives even finer distinctions than your three. Are you just complaining about semantics and the evolution of the language, or is there actually some point to using your terms instead?
