Saying, "Kill 'em all and kill 'em good!" is fun and all, but it is a cheap cop-out as far as an answer goes. The most common answer I hear is, "Make the price too high for them." That works for a speeding ticket, not a religious ideology. Can anyone draw a line in the sand as to when the cost would be too high for you to give up your 2A rights? What about your religious beliefs. I have a feeling that people killing you and others like you for what you believe, isn't going to make you any more likely to just up and believe something else.

Before people come in and start calling me a liberal and trashing me, I agree that this enemy should be engaged and eliminated, so save all the rhetoric for another thread. However, the simple question of "How do you fight an ideology with weapons?" is an interesting question with potential for some pretty deep and complex discussion well beyond "Shoot their faces off!"
