Thanks for your well thought-out comment. As it happens, you raised several points that will be covered in the seminar thing I'm giving at Anarchapulco at the end of the month, about the psychology of statism. Yeah, people should be "arguing" for the benefit of the OTHER person, not just to "be right." Although, as you mention, sometimes it's for the benefit of quiet spectators, more than for the "opponent." But if the goal is not spreading understanding, then it's not worth doing.
