The frustration for the atheist is to have to see that Christian fundamentalists suffer essentially the same problem of the Islamist fundamentalists, and to have to watch these Christian fundamentalists jump on board when it comes to pouncing on Islamist fundamentalism. It's kind of funny in a despairing, hopeless sort of way. For the Christian fundamentalist, it is a matter of having the basic sense of seeing the one true God, the right one, and of course Islamist fundamentalists feel the same way. What is an atheist to do?, except feel that the world is crazy.
