Remember the furor over liberal political correctness? Yes, some of it was over the top — but it was mainly silly, not something that actually warped our national discussion.

Today, however, the big threat to our discourse is right-wing political correctness, which — unlike the liberal version — has lots of power and money behind it. And the goal is very much the kind of thing Orwell tried to convey with his notion of Newspeak: to make it impossible to talk, and possibly even think, about ideas that challenge the established order.

Thus, even talking about “the wealthy” brings angry denunciations; we’re supposed to call them “job creators”. Even talking about inequality is “class warfare”.

And then there’s the teaching of history. Eric Rauchway has a great post about attacks on the history curriculum, in which even talking about “immigration and ethnicity” or “environmental history” becomes part of a left-wing conspiracy. As he says, he’ll name his new course “US History: The Awesomeness of Awesome Americans.” That, after all, seems to be the only safe kind of thing to say.

Actually, this reminds me of an essay I read a long time ago about Soviet science fiction. The author — if anyone remembers where this came from — noted that most science fiction is about one of two thoughts: “if only”, or “if this goes on”. Both were subversive, from the Soviet point of view: the first implied that things could be better, the second that there was something wrong with the way things are. So stories had to be written about “if only this goes on”, extolling the wonders of being wonderful Soviets.

And now that’s happening in America.
