You know You know [SIZE=+2]He's Not Black[/SIZE] [SIZE=-1]By Marie Arana Sunday, November 30, 2008 [/SIZE] He is also half white. Unless the one-drop rule still applies, our president-elect is not black. We call him that -- he calls himself that -- because we use dated language and logic. After more than 300 years and much difficult history, we hew to the old racist rule: Part-black is all black. Fifty percent equals a hundred. There's no in-between. That was my reaction when I read these words on the front page of this newspaper the day after the election: "Obama Makes History: U.S. Decisively Elects First Black President." The phrase was repeated in much the same form by one media organization after another. It's as if we have one foot in the future and another still mired in the Old South. We are racially sophisticated enough to elect a non-white president, and we are so racially backward that we insist on calling him black. Progress has outpaced vocabulary. To me, as to increasing numbers of mixed-race people, Barack Obama is not our first black president. He is our first biracial, bicultural president. He is more than the personification of African American achievement. He is a bridge between races, a living symbol of tolerance, a signal that strict racial categories must go. Of course there is much to celebrate in seeing Obama's victory as a victory for African Americans. The long, arduous battles that were fought and won in the name of civil rights redeemed our Constitution and brought a new sense of possibility to all minorities in this country. We Hispanic Americans, very likely the most mixed-race people in the world, credit our gains to the great African American pioneers of yesterday: Rosa Parks, W.E.B. Du Bois, Martin Luther King Jr. But Obama's ascent to the presidency is more than a triumph for blacks. It is the signal of a broad change with broad ramifications. The world has become too fused, too interdependent to ignore this emerging reality: Just as banks, earthly resources and human disease form an intricate global web, so do racial ties. No one appreciates this more, perhaps, than the American Hispanic. Our multiracial identity was brought home to me a few months ago when I got my results from a DNA ancestry lab. I thought I was a simple hemispheric split -- half South American, half North. But as it turns out, I am a descendant of all the world's major races: Indo-European, black African, East Asian, Native American. The news came as something of a surprise. But it shouldn't have. Mutts are seldom divisible by two. Like Obama, I am the child of a white Kansan mother and a foreign father who, like Obama's, came to Cambridge, Mass., as a graduate student. My parents met during World War II, fell in love and married. Then they moved back to my father's country, Peru, where I was born.
