Americas views on race are very weird. Race is a social construct. It was essentially a binary view on race. There were blacks and then everyone else. Thats why you could marry Mexicans or Indians but not blacks in many states, historically, if you were white. This changed when Americas immigration opened up to people from Asia and get central. But as those groups assimililate we are going to revert to the old style view of race. Black and then everyone else. So when people say white culture they really just mean mainstream American culture.
