Middle Easterner's, Arabs, etc. are members of the Caucasoid race. Doesn't that make Bin Laden a white man?

If a person doesnt fall into the Black or Mongloid race, they are automatically Caucasian. Which is kind of dumb, because alot of the Middle Eastern and South Asian countries have people who are whiter than white people, blacker than black people, and some people who are brown.
