Yes, but when discussing the "religious aspect", what's important is being surgical. There are two ways to look at this and it seems to be our fundamental disagreement. One is that the Dog (Islam) has fleas (ISIS). The other is to say the Dog (Islam) creates the fleas (ISIS). The issue is that you'd combat the two situations very differently. If you believe a Dog has fleas, you bathe them in medicated shampoo in order to protect the dog and kill off the parasite. If you believe a Dog creates fleas, then you put down the dog.
There's no treatment if Islam creates ISIS. You can't cure that. It will just keep occurring. On the opposite end, the one I find myself on, if you believe that ISIS co-opts Islam because it finds Islam to be a suitable host to feed off of in the region, then there are plenty of ways to combat that.
A lot of ways, we're currently doing. Kill as many as possible, without hurting collaterals (something we're still not great at, but better than we used to be). Hold up those who follow Islam but who are not radical, rather than painting all Muslims with the same brush. Enlist those who follow Islam who are not radical to help in the propaganda effort against ISIS and in the ground war against them.
And one key way we are not. Leave the region alone to resolve it's own issues, while containing it's ability to effect it's neighbors.
