Ugh, this again? Before civil rights if you had one drop of black blood, you were black. You couldn’t use white water fountains or lunch counters and heaven help you if you fraternized with white girls. There’s a book called—Life on the Color Line, by the current president of the University of Cincinnati, it’s his autobiographical account of growing up under segregation. Here’s the thing, if you saw the author you would say he is white. But one day he moved to a town where people knew that his father was actually black, and suddenly his life changed and he couldn’t do all the things he used to take for granted. Overnight, just because people knew he had at least one drop of black blood, he became a black man and subject to all the racism that went with it. In the post segregation world racism is directed against anyone who is visibly different, and Obama is visibly different. He has experienced racism (and he still does), he has had the experience of being African-American. Finally, many, if not most, African Americans are multi ethnic. They have Native American and white ancestors (and other ethnicities as well). Go find Strom Thurmond’s daughter and ask if she’s African-American. Or any of Thomas Jefferson’s African-American descendants.
