That's interesting, in the other thread where this conversation started
@Raees said asking moderate Muslims to accept that the Quran is not literally true and infallible is unrealistic.
Listen, Im no expert on this, Im not Muslim, I was not raised Muslim. I have read a bit about this and the argument I am making here is one I lifted directly from a book and am simply passing on because I found it interesting - and, I have to admit, compelling. But I am not saying it is 100% correct, or that doing what I have said above will solve things. Having said that, I am given to understand that Islam is a fairly black and white religion, that even mainstream Muslims understand the Quran to be the dictated word of god and that it is therefore correct, 100%.
But if Imams came out and said what you say above publicly, that the Quran should not be read literally, but be interpreted, and that it was OK to ask questions about doctrine and question the validity of some of God's words, and if that became the mainstream position of the religion as a whole - as it is in Christianity - I think it is fair to say over time you would get less Islamic terrorists.
