Fallen away Muslims are one thing; those who practice it are quite another, and the worst of the worst, ARE the advocates of Wahannism!
My high school class lost over 20 on 9/11. Most were fireman (one was a Port Authority PO) I'm sure you, like myslef, got worn out by all the funerals, and memorial services that we all had to go to.
No, another 9/11 is VERY unacceptable. And I'll be damned if the PC crowd tracks us right into another one.
As for Islam, even the most benign follower believes the worst of islams tenets, the worst actively carry them out. The ones that fall away are the ones that see islam for what it really is--a cult of death.
