Too bad people see with their eyes and not with their microscopes. Sure, there is more genetic variance in the human DNA in Africa than in Europe. But to the white slave masters and racist Southern governors in the 20th century, that fact hardly mattered. They used skin color to classify, repress race perception and embed that perception with negative attributes to stifle wages and segregate schools to retain power. Science means nothing to them; perception everything. But I know what you mean.
