There is no systematic violence in the wild, but, instead, momentaryexpressions of specific passions. This exposes one of the major fallacies of pacifist ideology. Violence, in itself, does not perpetuate violence. The social system of rationalized violence, of which pacifism is an integral part, perpetuates itself as a system. Against the system of violence, a non-systematized, passionate, playful violence is the appropriate response.
Violent play is very common among animals and children.
Chasing, wrestling and pouncing upon a playmate, breaking, smashing and tearing apart things are all aspects of play that is free of rules. The conscious insurgent plays this way as well, but with real targets and with the intention of causing real damage. The targets of this ferocious play in the present society would mainly be institutions, commodities, social roles and cultural icons, but the human representatives of these institutions can also be targets - especially where they present an immediate threat to anyone's freedom to create their life as they desire. Rebellion has never been merely a matter of self-defense. In itself, self-defense is probably best achieved by accepting the status quo of its reform.
