These threads involving Islam are always fun to watch from afar. The same usual suspects show up trying to explain away some horrific or incomprehensible event while quoting the Quran or Haddiths, and never actually succeeding in coming off as either reasonable or intellectually honest.
I'd wager any sum that not a single interpretation of Islam, no matter how liberal, will ever make sense to the majority of citizens in the Western world. Samuel Huntington's Clash of Civilizations is a great primer on this subject and should be read by anyone who has interest in Islam's integration with Western culture.
If we're talking about integration of Muslims into the west, then I reccomend you read the Myth of the Muslim Tide: Do Immigrants Threaten the West by Doug Sanders
Even if you have an argument regarding Muslims in the Middle East, you hardly have one regarding Muslims in the West and whether they are some sort of menace that has to be expelled. He goes over how similar things were expected of, say, Irish Catholics immigrating to Britain while the IRA was still very much at large
Found a link that goes over some of ideas he argues against, quoting straight out of the book, although the actual book has much more in it.

Finally, just from the title, I find the book suspicious. The idea of a clash of civilizations is one that seems to oversimplify things for a catchy headline. As someone has already mentioned, the middle east is hardly one unified civilization, and traveling through different countries, like Turkey, Iraq, Iran, Saudi Arabia, Dubai, etc., you get an understanding that things come in shades of grey.
Had to laugh when I saw this because I remembered Stereogatari's comment about smartly dressed clean shaven Pakistanis and there they are beating and burning effigies and generally being just as intolerant as the bearded crazies.
Or they could be the people in this thread, protesting against extremism
