Just how many "blacks" in this country do you think are pure black with no other blood mixed? The truth is most blacks have some white, or other type, of ancestry. White is the predominate other blood mixed with black. All people who look black call themselves black. Could you see some one like Bozo trying to pass as white? Nope, wouldn't work. Regardless of their ancestry, people with brown and black skins and with negro blood are called either black or, misleadingly, African American.
Please note I did not say they should try to say they are white, either. I totally understand very few “blacks” are fully so throughout their ancestry. The construct of “race” is as much cultural as it is anything remotely related to sciences like genetics or anthropology.
Examining Obama’s own writings verifies my point. He was raised as a child of mixed race in a white world, especially after his grandparents took him and his mother in due to her illness. He only took on the “I’m black” moniker when he determined that it put him in better standing for special consideration in school and politics. However, he had/has no cultural link for “keepin’ it real”. Thus, my point of the first sentence in my first post in this thread.
