Interesting, thanks for posting. I have come to the same conclusions as your two main points: 1) liberals want power and control or they want to be controlled; and 2) they like to help others not out of sympathy but of a need to feel superior.
I have been trying to figure out their belief in global warming and you make an interesting point. I had decided that belief in global warming was all about group think and peer pressure and fear of being branded as something other than a true liberal if they were to question conventional wisdom. But, as you mentioned, it probably has something to do with their desire to “fix” the world. And, they probably like the idea of having control over the weather too.
Tribes are self-organizing systems, like puddles of water. Water can easily flow in, but it's harder to flow out.
So some scientists began the big lie because they wanted this or that agenda - you'd need to waterboard Mr. Mann to find out exactly. That was step #1. But other scientists got dragged into it also, and I think most did not suspect anything; they had little reason for suspicion at that time. So that was step #2. The tribe was formed. And then, when all the current data failed to fit the theory ... they declared the data wrong. That was a bit overboard, but many of conscripted scientists had to either go with the deception or to bury their careers. And so the lie continued. Since last week several of those lower rank scientists, "foot soldiers," as they define themselves, already published articles that seek to explain their inaction.
