And before anyone leaps in to cry, “there is no single white culture!!!!’, note that there is also no single Arab culture or Japanese culture, but asking about them wouldn’t get people freaked out. Part of white American culture is assuming that white is normal, and everything else is an aberration. News stories will specifically mention something like the black president, or a black mayor, or a black Navy officer. If the subject is white, no mention need be made. If not, their race is spelled out.
