About Benguin's point--
But this is exactly the problem. The IDiots insist that their view be taught as science in science class. And digging deeper into the Wedge's (the ID movement's self-description) motivations, they're really not interested in contributing to science with scientific studies--they want to replace methodological naturalism with what they call theistic science, an oxymoronic endeavor that includes the supernatural as part of its basis. Because of this, they will never be satisfied with their material being presented merely as a religious view; they want it (eventually) presented as the One-and-Only-Truth. I agree that ID (and other forms of Creationism) are valid topics for courses in philosophy, religion, sociology, and so forth. How much time is devoted to these subjects in public schools?
