I grew up in a town that was 6% Black - there really weren't enough Black people to justify any further type of delineation.
In some parts of the South, some Blacks break it down to; Black, brown, light, bright, Redbone, Creole, mixed,... .
On another blogger's page some commented that mixed-race Blacks weren't 'real' Blacks.
(In all honesty, I'm fine with that - people can call me whatever they hate (it has no real impact on my life).)
But what cracked me up was that these same 'militant' comments often dismissed Obama's Blackness while citing the works of other mixed-race Blacks (Frederick Douglas, W.E.B. Du Bois, Booker T Washington and mostly Malcolm X).
Dumb-asses. Black is Black.
(But Black is NOT limited to; ghetto, poverty, ignorance, victimization or and other negative stereotype.)
