Sarcasm is an adjusted stress reaction.

<sarcasm>But don't you know that talking to people who aren't there is ALWAYS a sign of insanity? And since God OBVIOUSLY isn't there, then all Theists are completely unhinged. QED.</sarcasm>

I'm reminded of the "proof" that God doesn't exist by looking at the English monarchy, who have been prayed for for centuries, and saying that because the monarchy has been full of rotters, therefore prayer doesn't work. I can't remember who it was who proposed this "proof" but claiming it was scientific is nonsense, since there is no control group to compare it with. Personally, the fact that the English monarchy still exists when so few monarchies have survived, is fairly good evidence that God does exist.
