Conveniently early in his essay on "defection literature", David Edgar gives the game away:It's worth reading it all.
"Just as past generations sought to reposition the fault-lines of 20th-century politics (notably, by bracketing communism with fascism as totalitarianism) so, now, influential writers seek to redraw the political map of our time."
Do we get the idea that describing the Soviet model, with its vast network of gulags and millions of state murders and total party control, as "totalitarian" was a historical error? Certainly, that's the suggestion left hanging like a two-pig-owning kulak.
Oliver Kamm also responds to Edgar.
