If Muslims want something that can be interepreted to promote civilized behavior instead of the barbarism, they're not going to find it in the Koran. Basically, these are people who really really want Islam to be compatible with modern civilization, and are willing to rewrite the whole thing if that's what it takes to get it. Personally I think they'd do fine with the Old Testament.

Um, the Old Testament is as immoral and bloody as the Koran.
If they're going to look to a newer morality, they SHOULD take the path the Jews have taken with regard to interpreting the Torah and Old Testament, in general.
