But there's something VERY powerful about 'black blood'. You see one drop can turn a seemingly white person black. Is there something weak in white blood? Or something more powerful in black blood?
The one-drop rule is an historical colloquial term in the United States that holds that a person with any trace of African ancestry (however small or invisible) cannot be considered white[1] and so, unless the person has an alternative non-white ancestry that he or she can claim, such as Native American, Asian, Arab, Australian aboriginal, the person must be considered black.
a tad bizarre sounding.
but still, if your mom or dad is white, and the opposite spouse is in fact black, you are in fact, half black and half white.
Also, half black/white has traditionally not really been treated well by either race.
I mean, Halle Berry is half and half. Her mom is white.
but i do see the quote/theory you are talking about
"After having many talks with my mother about the issue, she reinforced what she had always taught me. She said that even though you are half black and half white, you will be discriminated against in this country as a black person. People will not know when they see you that you have a white mother unless you wear a sign on your forehead. And, even if they did, so many people believe that you have an ounce of black blood in you then you are black. So, therefore, I decided to let folks categorize me however they needed to"
- Halle Berry
I personally don't consider people in that case one or the other. (I don't think you can ignore all that makes a person a person IMO)
