You should read “God, Philosophy, Universities” by Alasdair MacIntyre.
K, I'll check it out. But first, tell me how you have a dialogue with someone who believes the Koran?
Sura (8:12) - "I will cast terror into the hearts of those who disbelieve. Therefore strike off their heads and strike off every fingertip of them"
Sura (8:39) - "And fight with them until there is no more persecution and religion should be only for Allah"
Sura (9:29) - "Fight those who believe not in Allah nor the Last Day, nor hold that forbidden which hath been forbidden by Allah and His Messenger, nor acknowledge the religion of Truth, even if they are of the People of the Book, until they pay the Jizya with willing submission, and feel themselves subdued."
Convert, submit or die. Those are the choices Islam gives non-Islamists.
Robert Spencer does a good job here explaining Islam - Blogging the Qur’an Start at the bottom.
