I've got to disagree with you in that regard. Most blacks, unfortunately, refuse to see or just plain don't believe that black Africans sold other Africans into slavery.
What this race WILL show is whether or not lies and rhetoric (which McKinney had plenty of in the debate last night) will win out over truth and facts. And if the lies and rhetoric win out, then my faith in many of "my folks" will be diminished even further.
