This is an interesting read.
I've read "The God Delusion" and watch a couple of presentation by Sam Harris and they both seem to be really out of touch with what a typical person on the street believes about religion. Some of these stats seem to back this up

There are nearly 130 million American adults who describe themselves as Christians, but who are Christian in name only; their behavior includes little related to experiencing and expressing their alleged faith in Christ."
