In the Western world, books are everywhere and not considered that important. It's different in the Muslim world - at least for certain books. Here U.S. troops in Afghanistan burn confiscated Bibles in local languages so they won't be accused of trying to convert Afghans to Christianity.
And here Muslims in Greece conduct a violent march through central Athens in response to the alleged desecration of a Koran by a Greek police officer.
I don't think playing defense gets the West very far in this game. (Thanks to Jihad Watch.)
