The sad thing is that Christianity, which I think is a great philosophy on how to live life, will be damaged because a few of them are pushing this idiotic ID junk.
They're shooting themselves in the foot, and they don't know it.
I don't think Christianity will be damaged as a whole by ID. In the long run, Christianity will be strengthened as controversies like this refine it. The number of people who believe specifically in ID, as defined by the current controversy, is small and inconsequential. ID is a passing fancy and will fade away as more people come gradually to understand that evolution is a materialistic mechanism only and does not contradict matters of faith.
Christianity is not a philosophy. It is an understanding of the nature of reality.
