FklkaldkFlagwaving didn't change anything. Creative use of the media, direct action, both violent and non-violent, and damage to state pocketbooks changed things. Marching and flag waving are just ways of making people feel like they're doing something when really they're doing nothing very much. At best I'd say that protests offer encouragement to those suffering or doing real actions, in that way they're good but they're not an effective way of creating real change. A (non-violent) attack on the Olympic podium during the opening ceremonies, waving Tibetan flags, would be a good stunt but anybody who tried it would probably be shot before they got within a 1000 metres of it, still, as long as it was on live international TV it'd still be a good action - until people changed channels and forgot all about it.
