Bad idea.
We are looking at it from a race standpoint. Whereas many blacks identify with being black as an ethnicity.
Actually, the trend is towards full-employment for genealogists since the success of the melting pot is blurring racial and ethnic lines. Consider Akaka's Hawaiian parallel government initiative where you'd have to find (and presumably document) a single Hawaiian great-grandparent. As far as African-American ancestry, will we be forced to add back words like octoroon to the US Code? It is going to come down to that. Who will qualify for a "black" scholarship? Perhaps this is what SCOTUS had in mind when setting a date for the expiry of preferences. That and the statistical likelihood that Whites would then qualify as a bona fide minority.
Good point. The scholarship should only be offered to people who "think" white, not to people who are white...
