He might debate anyway. Swordmaker tried to debate me back in 2003 over the Shroud. I had posted that the Shroud could only prove that a man glowed in the dark after death, and Swordmaker took me seriously.
He tried to debate me once but I have a database of the people and players and papers. I know the subject. Apparently he goes to the conventions and has met some of the people. He is a believer. Facts do not matter.
I invite any reader here to click on Alex's links and see why I would take his discussion with me "seriously" and whether I agreed with the "glow in the dark" claim he made... or even with the premise of the article that started the thread which was entitled: "SHROUD OF TURIN REVEALS IMAGES OF TWO CROWNS OF THORNS"
