When will we stop defining ourselves by color? If your genetic make-up is caucasian and ******* then you are indeed bi-racial. My son is multi- or mixed- because his mother is of ******* (father) and aboriginal South American/Spanish (mother) union. But why do you resist the term? There is much racism in the "black" community over skin color.
My Ethiopian/Habesha girlfriend does not consider herself "black". My American co-worker, who is "black" told our other co-worker, whose parents immigrated from Ghana, that he was NOT "black" because he was from Africa, and "black" is an American thing. The labels are crazy, seriously.
Regarding the Ethiopians, there are two lines of thought. One is that some 2000 years B.C., Caucasians/Semites moved into the region and they have been mixed since. The other is quite different. Ethiopians believe that they are the cradle of mankind, as Lucy was discovered there. If you consider this as the center point of all humans, when people migrated to the different parts of the world, natural selection removed the weaker genes from the groups and we end up with white people in northern areas, darker people in central Africa, and Mongoloid-types in the other regions. Under this theory, what you find in the Habesha characteristics would be what we all looked like in the beginning. Each cell containing the combined language of dark skin, and light, large lips and thin, straight noses and wide, round faces and narrow, curly hair and straight.
And as food for thought, what do you think about Indian people who have extremely dark skin? Are they "black"?
