Hunger has forced me out of my sanctuary. I must forage for food or starve. Unfortunately, the radiation outside is quite strong today and I may receive a lethal dose.
I think what bothers me about the FSM style of argument is that it's such a childish argument. "You can't prove me wrong so my intentionally silly theory is just as valid as your millenia old religious beliefs!"
I'm not arguing in defense if Intelligent Design, just scorning the FSM nuttery that's popped up.
