Remember everyone, "Extraordinary claims require only the most minimal, barely-measurable and irreproducible evidence."
David, I think if you looked into Vampires with the same standards, you would find believing in them credible. To me this a lot like the person who will use rational thinking to dismiss belief in the Loch Ness Monster, claims of New Age levitation, and so on, but think it is immoral to use the same thinking regarding the extraordinarily outrageous claim that a guy named Jesus came back to life after being dead then flew up into the sky.
Or, as mentioned in a recent Randi commentary, how some association of chiropractors can condemn someone for practicing fraudulent healing.
