Lord J-Bar is much, much more optimistic than I am.
Even considering how clever ID advocates have been, all it takes is knowledge to defeat ID. Once a person understands science, it’s easy to see ID for what it is: theology. Plus, the public needs to know why ID came to be. It doesn’t come any clearer than the Discovery Institute’s document, “The Wedge Strategy” (you can see it here), where they proclaim that the purpose of ID is “nothing less than the overthrow of materialism and its cultural legacies” (“The Wedge Document,” Introduction). Once the public realizes this, ID will no longer be an issue and will go by the wayside. However, one can never let down their guard. ID supporters have proven time and again just how effective they are at influencing an ignorant public.
There’s an important ingredient of the recipe missing there: in addition to understanding that ID is theology, they have to understand that that is a bad thing. I suspect the majority of the IDists already know that it is a strategem to grant a god the privilege of being scientifically credible…the only issue is that they know you’re not supposed to admit it.
