There is an agenda by many immediately biracial people to make them a seperate & distinct category from other black people - even though 85% of black americans have "racially mixed" roots.

Bob Marley was a person of mixed decent who choose to align himself socially, culturally, politically with the blackest among us. And make no mistake about it...that played a role in his choice of mate.

As for the tons of issues..well:

1) in a color struck, color caste world with white on the top of the totem pole - mixed race (as the intermediate btwn black & white) gets elevated to a higher status than nonmixed black. Not only within the white community but within the black.

2) Historically, black/white, black/whatever mixed people have served as a buffer or middle class - South Africa today being an example.

3) confusion as to what black is & means.

4) divided loyalties. Its hard to present a unified front when you're torn btwn 2 sides. Hence why many of these biracials want a seperate category...they don't want to pick a side (unlike Bob Marley, Malcolm X, Adam Clayton Powell, etc.)
