Most of the questions here are about pseudoscience, such as homeopathy and anti-vaccination. Are other forms of fringe theories, such as Gavin Menzies' 1421 on-topic?
I think so. In my opinion, all crackpot theories are on-topic. I'm sure at least some people would like to refute all the 911 truthers' theory and that falls under the pseudohistory umbrella.
