I'm looking for a certain quote I think I may have read on either this blog or Overcoming Bias before the split. It goes something like this: "You can't really be sure evolution is true until you've listened to a creationist for five minutes."

Ah, never mind, I found it.

"In a way, no one can really trust the theory of natural selection until after they have listened to creationists for five minutes; and then they know it's solid."

I'd like a pithier way of phrasing it, though, than the original quote.
