"Our aim is not to overthrow the state, but to ignore it. Anyone who wants to continue to support the state and obey its laws is free to do so, so long as they leave us alone. Our goal is to build the kind of society we want, and prevent the state from overthrowing us while we’re doing it. The last person out of the state can turn off the lights." - Kevin Carson

To some anarchism is the idea of a completely voluntary society. A violent overthrow of the state is against this idea.
