Ya know what they say don't you? One tiny drop of blood from a person of color makes you non-white! What if we are all just different hues of black from lightest/whitest to darkest/blackest? What happens then? Of course you also have Mongoloid as well. The three distinctions/separations are CAUCASIAN, NEGRO(ID), MONGOLOID. Centuries of changing societies have come and gone and who knows how intermixed we are? What would racist whites do if they were to find out they had lotsa non-whites in their ancestral chain going back however long ago it was?
