Dana writes a very nice article on what happens when a pure rationalist enters the world of fanaticism.
He didn't have a chance. That's the thing about the Scientific Method, you either stick with it or you don't. Nothing inbetween. You can't use it as a club to disprove nonsense, because the public can't tell the difference. All you can say is that it is not SM and therefore outside the realm of Science.
However, there are always people such as warmists who define Science as outside the SM. Their audience is the public, and they win an argument every time. Stay away from these people!
