Well, that's certainly how it should work, but alas often times people will believe what they want to in the absence of good evidence why they should not (and sometimes, distressingly, even when they have such evidence). Peak Oil seems a bit different to my mind than most of these science spats because it has the potential for profound consequences in all of our lives, raising the stakes a bit. These guys are obviously battling for the "hearts and minds" of the crowd, so why should we just "flip the bozo bit" and walk away, grousing all the while about the share of airtime they are getting? We know better. Not everyone does.

By the way, I wasn't really suggesting the piece on the history and science of oil exploration as a direct response to these guys, but as an educational piece like the kind we get each week on the technology of drilling. It would have, however, the beneficial side effect of giving us ammunition to counter our own close friends and relatives if they try to pull this abiotic oil garbage on us over Thanksgiving or elsewhere.
That is how the media frequently handles it. They find two people with opposing views, and let them argue it out. The assumption is that each persons argument has some validity, and therefore the public will conclude that the truth must lie somewhere inbetween. I suppose you could do a reductio ad absurdum by considering an argument between an astronomer and a member of the flat earth society. Or perhaps a professor of mathematics and a child arguing whether 2+2=4 or not. I guess my point is that the media is for the most part scientifically illiterate. Frequently when they have debates between a mainstream view and I guess what I would call a radical view, they have a hard time seeing that there is this imbalance in the relative weights of the arguments.
Well, my experience with most people is that wishful thinking can not be refuted with rational arguments it, it is simply impossible. By simply giving this guy an airtime you will actually support his cause because people will choose to believe him no matter what. The only way to give the red pill to the majority is a nice crash with reality.
