The wiki arguments are made by someone professed to be a blacksmith apprentice that alone by many standards of verification prime example being Justice systems of alot of countries save for Mexico go by. It's equivalent would be a 1 year student in forensic science testifying as a professional in the field of forensic science over gun shot trajectory and blood splatter in a murder where as a professional's opinion would hold more if not concrete merit.
Since credentials on the Internet are hard to check, I don't care very much for what someone claims to have and what others think of it. Anyone can claim anything, and I prefer to listen to the arguments on the topic instead.
