It takes time for most people to build up to that level. Also, any civil unrest generally needs a smoke screen of legitimate, law abiding protestors.

Just getting people into the habit of going out to actually protest would be a big step. The more people do it, the more socially acceptable it becomes. The more socially acceptable it is, the more people will turn up. Eventually, it starts hitting critical mass, which scares those in power. Until then, a few broken windows, or burnt cars, are good propaganda optics to drive your support back into their living rooms.
