One drop of black blood and you're black. That was the rule. That's what kept the wall between whites and blacks was this one drop rule. So I was raised with absolutely no ambiguity about that.
The privileged position of whiteness doesn't allow for someone with one drop of Negro blood to be considered white, which allows whiteness to be a fairly pure category while blackness has to absorb an expansive reality of representation.
Negro blood is sure powerful, because just one drop of black blood makes a colored man. One drop--you are a Negro! . . . Black is powerful.
I have spent my whole life earnestly believing the fundamental American dictum that a single 'drop of black blood' makes a person 'black' primarily because they can never be 'white.'
America is the only country in the world that classifies as Negro any person who has one drop of African blood in his or her veins.
Many people believe that determining who is 'black' is rather easy, a task simplified by the administration of the one-drop rule. Under the one-drop rule, any discernible African ancestry stamps a person as 'black.'
In America one drop of black ancestry makes you black.
There's a thing called the 'One Drop' theory in African-American culture, which is if you have one drop of black blood in you, you're black.
