Intelligent Design Creationism

I think what you're failing to appreciate is that talking with creationists involves two issues:1) Why are creationist positions wrong?2) If the positions are wrong, why do creationists promote them?All the "ad hominem" I think you're referring to is actually the answer to the second question, not the first. When we make statements about creationists that are a little less than charitable, it's not to point out why their arguments are wrong - we've done that already with evidence. When we point out the dirty credentials of folks like Hovind or Johnson, it's to explain why creationist ridiculousness still gains purchase on susceptible minds.

Wait... what? JP, do you need to be told where babies come from?

Your baby didn't gestate in a uterus?

So what you're saying then, is that if life is the product of intelligent design, nature doesn't exist?That's the pretty obvious extension of what you're proposing:1) Any life that is intelligently designed is not natural.2) All life is intelligently designed.Therefore, you must obviously conclude that nature doesn't exist anywhere. What, then, is the word "nature" supposed to describe?
