Radicals used to long periods in the wilderness are reluctant to kick a movement that at least garners some minority. But that can be a weakness, too. It is pointed that the current wave of protest movements have failed to substantially impact upon the extensive austerity measures being imposed in Greece, Spain, and elsewhere in Europe. Observers make the point to me that the people gathered in the square in Spain were cutting themselves off from the debate that was taking place in the elections over the austerity measures, rather than taking part. I am not sure that anyone in Britain is listening to the Occupy LSX people.
If there is no critical self-reflection, then there is no movement.
