Islam is a governmental religion that the vast majority of Muslims do not follow even close to correctly. Islam is a religion of violence. But most Muslims and Muslim clerics have already almost destroyed it by turning it into a religion of peace.
Help Muslims kill Islam the rest of the way by freeing them from the violent requirements of their religion.
Don't kill the Muslims. Rather, help the Muslims kill Islam the rest of the way.
I doubt the religion can be killed. Many said Christianity would die out but it seems to be seeing a resurgence. What we should be doing is help them get through their own "reformation" if that is even possible. Granted, Reformation really didn't eliminate religion being problematic (just look at Protestant vs Catholic conflicts in the past) but it's a start. Weaken the hold of the clergy over the smallfolk.
Reformation would also allow a flourishing of new sects. Considering that most people are moderate anyway, they'd probably go along with moderate sects and there might be more moderate sects to begin with.
When religion have to compete in the free market of faith, they adapt to the people rather than force the people to submit to their will.
BTW... I don't want to kill any of them, as long as they don't attack me.
I also don't want to live near them. Not that I believe they are all bad but their level of tribal mentality is disturbing. You're always worrying you might offend someone. And it's not like I would be able to live near them in the first place. They tend to form ghettos which in time become a no-go for infidels.
