I recently
saw an interview between Richard Dawkins (whom I find, personally, to be quite irritating and condescending, but my opinions can be saved for another thread) and the Bishop of Oxford.
The Bishop, apparently along with most Christians in England, did not refute the theory of Evolution. He quoted from a previous debate on the subject where it was said that God didn't simply create the world, but "makes the world make itself." Isn't that enough for wacky ass Christians here in America? I guess not, and my explanation is quite biased, but I suppose it should be offered anyway.
The Roman Catholic world seems to support much more philosophical and free thinking than the protestant Christian denominations. Catholics seem to me to be more flexible, hell, they've been flexing since the beginning: Christmas and Easter were both
merged with pagan holidays in order to convert more "barbarians" in western Europe.
By contrast, Protestants, which are the majority in the US, take the bible very literally and very seriously. Therefore when posed with evolution they fiercely refute it, simply because that concept doesn't come up in the bible.
