How do you deal with ISIS?

I think about it. I've done my share of 'brain salad surgery' on them. It's an extreme ideology that thrives in an angry religious atmosphere. It appeals to the worst that is in a human being. Religious narcissism, misogyny, moral fascism, blood lust, power lust, and plain old hatred and rage; combine that with the political and economic meddling of the west in affairs that are not their own, and you have groups like ISIS. In many ways, it is like a street gang. It takes advantage of weak minded and disturbed people who want to BELONG to something greater than themselves.
So that's it. I just think about it, and hope that my tax dollars might somehow help to keep it out of my front yard.
