The Skeptic's Bible is an excellent project to show how silly the Bible, Koran and Book of Mormon are if you take them literally.
Of course too many people, the Bible, Koran and other books are not to be taken literally, or only selectively literally. A bit like political manifestos?
The trouble with this view is that it is there is no guidance as to which bits should be taken literally and which bits shouldn't.
Personally, I always find the more literal approach to be the more sensible.
