Why would those in a position of power care how the rabble defines Black? It should be of no consequence.
If you (not you specifically, but generally) feel that the Blacker-than-thou crowd has it wrong, then you have no worries because right will prevail in due time. Personally, I think those Black folks need other Black folks more than they admit. That, despite their opposition to much of what is believed by the people who frequent this board, they come to places like Africanamerica regularly.
Contrary to vehement public proclamations as to what is wrong with the overall ideology of the participants, the opposers take precious time out of their day to be in the midst of those they oppose and often look down on. They will be the first to tell us that they don't mind being without the presence of other people of African descent, and in the next breath insist they will continue to engage the members in conversation (such as it is) and have a compelling desire to influence the "direction" of the group.
Would it make Condoleeza tha' Skeeza feel better if we all sent her a letter telling her she is hereby certified to be as black as coal? Will she and her supporters sleep better at night?
