Any particular direction?
I have never blamed the 'leader' for the behavior of his followers. Not even the little general himself. Animal instinct is always much more powerful in the group, where the individual loses his mind, and effective leaders know how to direct those instincts. It's still not the leader's fault. He is merely exploiting a vulnerability. They prove that psychology is a science and show its biological, instinctive roots, some of the time, inadvertently, because some of them don't understand the mechanics either. They just know which buttons to push.
Alinsky, getting back to him, is running a business. Free market, remember? In the grand scheme, beware of the buyers... always. Idealism, it doesn't matter whose, may be good for business, but it really isn't good for the psyche. It inevitably ends in madness. To me it is self evident.
