It is hard to over-emphasize this. So many of the political misunderstandings of how movements operate stems from not seeing Movements as educational 'institutions,' a function which (up to a point) is far more important than whatever effect they have on state behavior. Demands MUST BE formulated with this in mind -- that the main purpose of the "demands" is to trigger educational discussion and thought WITHIN the movement itself. And this, incidentally, is perhaps the main way in which a left political movement may prefigure the society it aims at.
