Have you noticed how self-proclaimed (and self-satisfied) agnostics often sneer at us arrogant, over-confident atheists without expressing any parallel contempt for the Pope, Rick Warren, the imams, and so on for their similar if opposite avowals of certainty? In the future I plan to insist on agnostics being equal-opportunity sneerers.
You should note that I have repeatedly said that excessive certainty is a hallmark of both fundamentalism and fundamatheism alike. As Einstein said, ” [t]hen there are the fanatical atheists whose intolerance is of the same kind as the intolerance of the religious fanatics and comes from the same source.”
Six of one, half a dozen of the other.
