Is there any way to quantify the effects of a couple hundred years of social injustice, including a lengthy period of goal-focused
breeding on the parts of slave-owners?! Yes, they treated their fellow human beings as livestock and bred them accordingly...for certain
desired attributes. They wanted strong backs, not particularly strong minds. That embarrassing chapter in American history was followed up by another century of segregation, during which educational resources and opportunities for blacks were significantly stunted as compared to nearly all other ethnicities in the United States.
And now, after fewer than three generations with a woefully inadequate affirmative action program in effect, we have a group of ignorant whites bitching and moaning based on "a gap" which all the evidence suggests has everything to do with environment and nothing to do with race.
