Well identity is all mind and no matter. There is no tribe in Africa named Black and no unity either.There is no place called Whiteland in Europe and no language known as Whitish. Physical genetically inherited traits can be grouped in to race,but its just a term for communication. Colorism has existed as long as racism. In Africa many of these people truly hate each other and would insist they are no the same race. Mulattoes, Freemen in New Orleans were four times as likely to own a slave than a "white" person. Those inherited traits mean almost nothing in regard to intelligence or personality. There is only one homo sapiens, but canis lupus and canis familaris are two subspecies.
