I think some of these guys get into some philosophical conversation with their Dad in the car ride home from church or something, and they think they've come up with something deep. Then they come here, and everyone is running circles around them with prepared arguments, references to actual books, authors and thinkers, and an existing knowledge of every "new" argument the theist is working hard to come up with. And also, of course, theists are at a disadvantage because they don't really understand what atheism means to atheists.
Then the guy disappears to "prepare" and never comes back.
