Is God Unconstitutional, Part 1: Johnson, Phillip
In the article, titled "Is God Unconstitutional: The Establised Religious Philopsophy of America," Johnson's criticisms of "naturalistic assumptions" become part of a much larger campaign against cultural "modernism" and its tolerance of sexual promiscuity, materialism, atheism and other things - including Darwinian evolution - that evangelical Christian audiences tend to find repugnant.
It appears then, that the ID movement is trying to get away with promoting specific, Christian cultural beliefs and values in secular, public schools - just as the creation science movement attempted.
