A major challenge is what is ID? Is it a scientific movement? Is it an apologetics movement? What type of “design” are they talking about? If ID is a Christian apologetics movement, it should not include Moonies or Raelians, for example. The ID movement is a self-identified big tent, which is fine, but instead of “I think this, they think that, and those others think something else, but we can all get along”, it tends to be marketing differently to different audiences instead of being upfront about the variety.
