I find it reminiscent of a religion in that adherents subscribe to certain ideals that can not be argued about ("it's the right thing to do" as the author says). My amateur psychologist analysis is that people need a higher cause, and in the absence of traditional religions they instead join political movements such as this one.
I too believe our brains are hardwired to be receptive to certain power structures/belief systems. Science can be a religion-- you be a zealot about anything if you try.
Global warming, true or not has all of the hallmarks of a religion-- which is why I think generally, religious folks aren't as receptive to the idea-- that need of theirs is already filled.
Didn't the pope talk about global warming?
Diversity is not a political movement as I understand it. How did you come to that conclusion?
