There is no problem with technical discussions either, the line here is the “no comment” (except vague ones) policy of Dr. Curry on the political ID of the core pro-warm science community that she has been part of for close to 30 years.
It goes too far, skeptics need to grow up but the truth is many skeptics are Green in nature as well. It’s clearly a divide in the skeptic community and the ability to minimize the political color of the AGW movement has been used to great effect.
The science for or against AGW has always been vague and weak, it’s politics that changes and is most important regarding policy. Tactically the image of the science “high ground” does matter and I understand and respect those skeptics fighting for it but it only matters as such due to the weak science backgrounds of the general public who could ever have bought the AGW proposition in the first place. AGW reflects a decline in social reasoning and poorer educational results. There is also the impact of government funding to create phantom science industries like AGW at work as well. It all came in a really good brochure and appealed to the baby boomer leftwing hungry to attack carbon interests despite how hypocritical or irrational the effort. AGW is like a modern hulahoop, burning your draft card or the Beenie Baby craze rolled into one. There are international narratives as well like scapegoating corporations or wealth that are standard fair in the third world. AGW is packaged to please a variety of mobs.
