I do not think you have really addressed Logos01's point, which I understand to be that the OWS folks are characterized by epistemic zeal for existing beliefs. Your strategy does not seem designed to alter that.

Instead, you suggest starting by affirming a bedrock zeal-inducing belief, making sure it pisses them off, and then (somehow) getting them to apply the insight that admitting that they are wrong about a lot of things is one of the keys to becoming less so.
