I am wondering if you are a young earth creationist or a theistic evolutionist with millions of years of men evolving. I hope you are the former.
The reason I ask is that I know one (unsaved) white supremist who without any hostility whatever will explain how over millions of years the white line had evolutionary advancement to a far superior degree than the black race, which barely made it past primate stage. And in the same way you can breed a line of dogs to be easily vicious; the Jews were bred to be exceptionally cunning and easily wicked. Hitler did not go far enough and the world needs another Hitler.
(This person is very nice to blacks and Jews, the way you would be nice to a pet or a horse or smile at the tigers in the zoo. You don't hate them and they have their place in the world, but they are essentially subhuman even if they can mate with whites).
When millions and millions of years of Darwinian evolution enters the equation, I don't think Christians have a leg to stand on to protest racism. Seriously, over millions of years, who is to deny the blacks barely got past the primates while the whites had many advantageous and superior mutations? Who can be Darwinian while also protesting white superiority as racism?
Since I know we all came from Noah 4,000 years ago, and I know white skin is a gift to make more Vitamin D in northern latitudes, and dark skin is a gift to prevent melanoma in more tropical latitudes, I have no problem regarding all races as equal in essence. But frankly I wish the Biologos people would remove themselves from the discussion. If we came from primates, then there can certainly be extremely varied degrees of development the last few million years. I can't figure out certain people who think Adam lived millions of years ago, and then decry racism. Where would the heresy be if Biologos is correct about human evolution?
