Because white isn't a race.

Are Greek whites? They are tan.

Are Irish white? they have the right color, but been denigrated for their race by other " whites ".

Are Egyptians white? Since color doesn't pick your whiteness, are Egyptians who have a lot of Greek descendance white? or being on the african continent cleanses them of that?

I just wanna be clear how much science i gotta ignore to exists in the "real" world.
