One, human beings are all ONE species.
Races are minor variations within that species.
Two, the argument that 'white' descendants are racially superior is fales for several reasons. For one, ALL present-day humans are descendants and therefore racially superior to their ancestors. And the descendant argument accepts as it's unstated premise that an evolutionary descendant is naturally superior to it's ancestor. I submit that this is not necessarily an established fact. We are ALL equal spiritually - dead in trespasses and sins.
