There are two types of disruption: violent and nonviolent. Violence is a traditional method. It is brilliant at getting attention and creating chaos and disruption, but it is often disastrous when it comes to creating progressive change. Violence destroys democracy and the relationships with opponents which are vital to creating peaceful outcomes to social conflict. The social science is totally clear on this: violence does not optimize the chance of successful, progressive outcomes. In fact, it almost always leads to fascism and authoritarianism. The alternative, then, is non-violence.
