Jesus - we now have several different camps of deniers
Doc's camp - still bringing up code - that wasn't used - still discussing 'climategate', even though it's been shown to be a non-event - still very political in his carbon-credit attacks - and still linking to wattsupwiththat - even though that's like posting links to Fox News for 'fair and balanced' reporting. At the very least - there is some positive take-away - this camp, though very reluctantly, has given up on the 'it's not warming' part of the discussion. This camp usually consists of intelligent people, but people too blinded by their political affiliations to change their minds.
Jaskalas' camp - this quite honestly is the 'I'm still going to use misleading/inaccurate/flat out lies' to prove my side of the discussion - oh, and by the way, it's still not getting warmer, the whole thing is a scam. This camp is basically the equivalent of the group that was of the opinion that 'smoking isn't bad for your health'.
Others - like this Xbiff clown - their camp is 'this science gobbly-beloved patriot is far above my thinking pay-scale, so I'm just going to say brilliant things like 'earth was warm before', or 'how could we possibly measure temperatures from the past', or 'it was warm for the dinosaurs, we'll be fine'. These are people whose personal thoughts are shaped by others - more than just their political affiliation, but their entire way of living. These are your poorly educated, sadly re-producing, can't think for themselves, Fox news-loving, GOP die-hards.
The 'left' has groups like this as well - however, they tend to stay out of discussions like this - common sense tells most people 'if I don't know jack about topic X, I probably shouldn't discuss it or offer my badly misinformed opinion about it' - but that doesn't stop the people in Xbiff's camp.
