As I said, it's not a criticism. I guess the difference is that for some interest groups the people who are looked up to are clearly separate from the community itself. And it's not a question of approving of them in terms of 'don't they do good work', which you might expect in enviromentalists. It's closer to martial arts in that it's looking up to mentor-like figures who are seen as further down the path of rationality. Though the related qualities of intelligence and productivity get attention too.
