Yes it is the right word, but politcally incorrect, this is according to my history teacher so don't get me wrong, but Nazi scientists created these terms in order to seperate the "race" of causian or whatever it's called, from the others, making it superior.
It's all nonence becuase race means different genetic material, or something along the lines, which means two races cannot reproduce successfully (A donkey and a horse can mate, but not sucsessfully, as in, their child will not be able to reproduce
).
But this word has been put into general use, so using it is considered right, even though it is wrong
Just trying to be politcally correct and racial aware (That is, avoiding saying something that may offended someone of a different "race")
