Our notion of what constitutes “white” and what constitutes “black” is a product of social context. It is utterly impossible to look at the delineation of a “Southern race” and not see the Civil War, the creation of an “Irish race” and not think of Cromwell’s ethnic cleansing, the creation of a “Jewish race” and not see anti-Semitism. There is no fixed sense of “whiteness” or “blackness,” not even today. It is quite common for whites to point out that Barack Obama isn’t really “black” but “half-white.” One wonders if they would say this if Barack Obama were a notorious drug-lord.
“Race,” writes the great historian Nell Irvin Painter, “is an idea, not a fact.” Indeed. Race does not need biology. Race only requires some good guys with big guns looking for a reason.
