Because the original post is rather quite lacking in any sort of logic and actually can be used (As pointed out by me and a_unique_person) to justify any sort of crank opposition as legitimate controversy. Its actually a rather quite simple case of reductio ad absurdum.
Yep, pretty much. The only real conclusion to come to is that a lot of AGW deniers have agendas that are not disclosed, and we'll probably never know what they are. Fears of their own mortality? Deep-seated feelings of inferiority? A desperately uneasy sense that the world is changing around them and that they can't control it, but that they somehow
should be able to? A never-ending attempt to be right about something,
anything, because life is not turning out the way that everyone told them it would, and their jobs are unstable, everyone is getting laid off, the house is mortgaged up to their ears, how are we all going to pay the bills, God, we've got to grab onto
something to obsess about! I know! A weird conspiracy theory!!
Anyway...Unfortunately, that is not the only occasion on which I've seen the exact same kind of logic being used around here. I finally just had to decide that I wasn't going to get involved in those discussions anymore. If an issue has 8,000 scientists, professional organizations, standard reference texts, basic reality, etc etc etc, on one side of it and a few self-appointed vested self-interests and lots of hysteria and name-calling on the other, then anyone with any common sense at all is going to know what's going on. At some point, you can lead a horse to water, but you can't make him think.
