As much asd I agree with Bush's statement that everybody should be exposed from different schools of thought and perspectives, I don't think that - if I could read his mind, which I can't - I would agree with his motives. Using the past as a frame of reference, I can imagine that this is just a way to get this kind of teaching into the classroom. I doubt that, if creationism and evolutionism were to 'switch places' (so to speak), he would be saying the same thing.
