Killing innocents is not all right. And fighting an enemy that is driven by irrational hatred cannot be defeated if we are also infected by that hatred.
In my opinion, the fight is not with the people of Islam but with a religion and ideology that is, at its root, dangerous. When its adherents are lukewarm, they are not particularly different than anyone in western culture.
But when moderates encounter imams who draw them to the core of the religion, a change occurs. When these lukewarm believers are ignited, they become explosive.
Of course. Fanatics in any religion can be dangerous.
