In my view - and I might be entirely alone in this! - I don't think that is what serious theology tries to do, Steve. Though I have to begin by saying what I think of as religious fundamentalists do precisely what you describe, whether they are Christian, Muslim, Buddhist or anything else.

The first question on religion should not be whether it is true or false, but whether the mindset of true/false is the applicable one in the first place. And for me it isn't. And it is where I part company with Dawkins because he believes it is the right one, and I don't. Once you do, you get into the situations where Abrahamic fundamentalists have to insist Adam and Eve is literally true, and that is in immediate conflict with science. Simultaneously Dawkins sits with fundamentalists in declaring anyone who claims to be a Christian (Jew, Muslim, ...) but does not assert Genesis as truth is a 'pick and mix Christian', choosing the bits they like and rejecting those they don't. I find this disappointing, Dawkins is far better than that.
