Orwell's Rejection Slip

Alan Jacobs weighs in on news that T.S. Eliot refused to publish Animal Farm for political reasons (the Russians were WWII allies at the time). Larison responds:

Would Animal Farm have offended the Soviets? I assume that it would have to have been offensive to them and was offensive, but why should a publishing house in the West care about that? What a telling and sad statement about the power of wartime political correctness that even a mind such as Eliot’s, which obviously had zero sympathy for the system being attacked in the novel, could reach the conclusion that he was not convinced that “this is the thing that needs saying at the moment.” When would have been appropriate?
