Even Obama himself seems to have bought into the nomenclature. In his memoir "Dreams from My Father," he writes, "I was trying to raise myself to be a black man in America, and beyond the given of my appearance, no one around me seemed to know exactly what that meant." You can almost feel the youth struggling with his identity, reaching for the right words to describe it and finally accepting the label that others impose.
It doesn't have to be that way. As the great American poet Langston Hughes once wrote, "I am not black. There are lots of different kinds of blood in our family. But here in the United States, the word 'Negro' is used to mean anyone who has any Negro blood at all in his veins. . . . I am brown."
Hughes was right. North America has been slow to acknowledge its racial mixing. Anti-miscegenation laws, which were prevalent in Germany under the Nazis and in South Africa during apartheid, were still the rule in a number of states here until 1967, a mere generation ago, when the case of Loving v. Virginia finally struck them down. The goal of those laws, unspoken but undeniable, was to maintain racial "purity," ensure white supremacy. It was not only undesirable, it was punishable for a white to procreate with a black. Or an Asian. Or an Indian. And yet a quiet cross-cultural mixing continued all the while. Even under Thomas Jefferson's own roof.
The explosion of "minorities" in the United States in the past half-century has guaranteed that ever more interracial mingling is inevitable. According to the 2000 Census, there were 1.5 million Hispanic-white marriages in the United States, half a million Asian-white marriages, and more than a quarter-million black-white marriages. The reality is probably closer to double or triple that number. And growing.
