"Anglo-Saxon Protestant, otherwise known as WASP, and American Black is always on the bottom, and what's in the middle depends on time and place. (Or as that marvelous rhyme goes: if you're white, you're all right; if you're brown, stick around; if you're black, get back!) Americans assume that everyone will get their tribalism. But it takes a while to figure it all out. So in undergrad, we had a visiting speaker and a classmate whispers to another, "Oh my God, he looks so Jewish," with a shudder, an actual shudder. Like Jewish was a bad thing. I didn't get it. As far as I could see, the man was white, not much different from the classmate herself. Jewish to me was something vague, something biblical. But I learned quickly. You see, in America's ladder of races, Jewish is white but also some rungs below white. A bit confusing, because I knew this straw-haired, freckled girl who said she was Jewish. How can Americans tell who is Jewish? How did the classmate know the guy was Jewish? I read somewhere how American colleges used to ask applicants for their mother's surnames, to make sure they weren't Jewish because they wouldn't admit Jewish people. So maybe that's how to tell? From people's names? The longer you are here, the more you start to get it."
