You have a point however I beg to differ in some respects. I think this is because I have known many Muslims personally. The ones I have met are of a liberal variety. They came to the US to get away from the crap in the Middle East. They hated it there and wanted to be free. They are happy to be here and have assimilated. The wanted to be free from shira law and the horrid repression of women. They also want to hang on to their faith. No, they are not the total picture. The test needs to be that if Muslims immigrate they must accept a Western philosophy. They must accept a Western justice system. If they don't want to do that then they need to be sent back. The Muslim faith has more variety that is seen on the surface. They are much like Christians in that way. Some are liberal, some are not. Not all Muslims believe in things like honor killing. A lot of how Muslims view the West has to do with the amount of education they have. The more ignorant they are the more they fall prey to the fundamentalists. Sadly the number of uneducated Muslims far outweighs those that are educated. That is exactly where the fundamentalists want to keep them. They are the ones they can get to strap on explosives for Allah.
The uneducated turning to extremism makes sense. But how do you figure they talked the Mohammed Attas into self destruction. Those folks from 9-11 were rich & well educated. : (
