In response to misanthrope, yes, we've read his fiction. Lewis' perfect theocracy was not a government by priests as most people conceive of theocracy. It was a government by God. It is impossible for a socialist to understand. They believe if you give people sufficient stuff, they'll be happy. Christians believe that if you allow God to make you a better person you'll be happy. The progressive socialist seeks a temporal kingdom or utopia governed by good smart people. The Christian seeks a heavenly one, full of good smart people governed by no one but God. Christians are the ultimate anarchists. We envision a world without any government at all.

Lewis well knew about Stalin's Communism and Hitler's facism having experienced a world racked by the depredations of both. But if you will check into the history of both isms, they began as government doing good on behalf of its people. Communism was supposed to be a worker's paradise; Nazism an Aryan one. The comment was a warning against Britain's own steady creep toward socialism.
