Correction 8/8/08: The original piece identified the Publisher, Cambridge University Press, as an American publisher. That was incorrect. Cambridge University Press is in England.
America is the land of liberty. It is the place where political expression is protected by law and custom. It is the freest nation on Earth... unless, of course, you wish to talk about Islam. Then, unless you bow and scrape, unless you assert its supposed peacefulness, unless you bend over backwards to make sure that you don't "offend" Islamists, you will be shut down. At least this is true if you wish to publish a book about Islam, it appears.
