You can lead some of the people to the barricades, for some of their time. But you can't keep them there, nor direct where they go next. Leaders fall; regimes collapse; bills fall due; milk boils over; babies cry; dogs bark; caravans move on; all the while, ideals are eroded by the day-to-day pragmatism of living.
Abstract agreements are no basis for action. Yes, things "should" be different, and more importantly, could be different. But there is no automatic right to have them made different, nor to impose difference.
There is no mind so closed as a mind that believes itself open. And liberal. And benign.
