Matthew Yglesias and Glenn Loury had a diavlog on Israel & the Congressional Black Caucus. Glenn brought up a paper he wrote back in the 80s when he was a neoconservative, Self-Censorship in Public Discourse: A Theory of “Political Correctness” and Related Phenomena. I’m still reading through it as I write, but seems like good stuff. Hopefully Anonymous would like it, it references Erving Goffman early on and uses a framework inspired by him.
