Dawkins begins by informing readers the shocking news that reliable polls report 35% of Americans say they are "born again." No wonder we have such a fixation on topics such as homosexuality, helping Israel, school prayer, (non)-separation of church and state, gay marriage, abortion, and intelligent design!
Interesting contradictions were then pointed out. For example, if the U.S. is a free country, it cannot also be a Christian nation. Similarly, the doctrine of the Trinity contradicts the idea that there is only one God. Still another - Iran has the largest Jewish community in the mid-East, outside of Israel, despite it's anti-Israel rhetoric.
The bulk of "Everything You Know About God is Wrong" is taken up with pointing out conflicting material within the Bible, referencing material left out, and the innumerable past and present perversions of religion - especially all the persecution and killing of "infidels."
Bottom-Line: The book has some good information, but is far too long. I prefer "God is Not Great," "Terror in the Name of God," "Why the Christian Right is Wrong," "Misquoting Jesus," "The End of Faith," "Jesus is Not a Republican," and "The God Delusion."
