I bring up the point I'm sure many don't follow the Quran so closely. I'm sure we can all think of many Christians who have committed the sins of adultery, who have worked on Sunday, and who have "coveted" things his neighbor owns. Some pretty weighty sins in the Biblical order, but not that much in the morals of the United States. Many old taboos seem rather silly in the modern world.
This is how one would defeat a religious enemy. You can't kill a religion. You can destroy a culture. A gradual westernization of the Middle East would do more towards eliminating radical Islam than military action ever did. Television, radio, fast food, and cheap consumer goods would do more to undermine the radicals than bombs and bullets ever could.
While this is probably true, the implication you're making is that if we would just stop bombing and shooting them, the radicals would stop bombing and shooting at us and would not interfere with our cultural re-make of their culture. This discounts the fact that they already routinely bomb and shoot ANYONE who doesn't agree with their ideas of proper comportment.
