The most laughable aspect of America's long war against racism, is the justification racist would always trot out--the specter of interracial union. I can remember being a kid and reading about black folks struggling for some small right, that, these days, we take for granted. So you'd have some black dude who'd been born a slave, in some one room shack, but had risen to become a lawyer, arguing for, say, school funding for black kids in rural Alabama. And then you'd see some bigot responding with, essentially, the following, "If we give the nigras school funding, they'll take our women! Do you want a nigra marrying yer daughter?!?!?"
I would read that and think, "What? The dude just wants some textbooks, WTF??" There's this great riff in Wattstax where Richard Pryor talks about Southern whites accusing a black dude of raping some white guy's wife. The guy brings out his wife and says something like, "The nigger raped her!" The assembled black folks look at the guy's wife who, let's just say is not Scarlett O'Hara, and go, "You sure??"
But in the white male paranoid mind, the deepest ambition of all black men lay between the two legs of some white woman--any white woman. And white women, of course lacking any real agency in the narrative, joyfully go along. Or are forcibly carried along. From that perspective, white racism really is a fear of a black planet--and (paradoxically) of white women.
Bigotry, in all forms, requires a shocking arrogance, a belief that other communities deepest desires revolve around your destruction. It is the ultimate narcissism, a way of thinking that can only see others, through a paranoid fear of what one might lose. The fears are almost always irrational. To go back to Chuck D, perhaps he was too cold when he said, "Man, I don't want your sister." But there was deep truth in it, the idea was, "Fool, this ain't about you and your fucked-up sexual hangups." In much the same vein when I read people complaining that gay marriage is a threat to traditional marriage, I think, "Fool, these gay motherfuckers ain't thinking about your marriage. This ain't about you and your hang-ups."
Coates mentions anti-Semitism, but making it more explicit, much of anti-Semitism rests on this idea of Jews as hyperpowerful -- pulling the strings of the entire world; an insidious cancer which if left unchecked will corrupt and destroy modern society.
I'm sorry to say that for the most part, Jewish lives are considerably less dramatic. We want the same things as most other people do, and live the same lives that most other people do. But the conceit is always there: the 1% of the population that was Jewish has always been seen as an existential threat to Christianity; and now is seen as an existential threat to humanity itself. And, again I hate to be this blunt but: Get over yourself.
