Memes of Production

We don't prevent or deal with rape in our current society, you do realize? It's one of the most ignored crimes.

I'll link and quote the relevant part of an anarchist FAQ for you:

When people object to anarchy, they often ask about those who would steal, murder, rape and so forth and seem to assume that such people would be free to act as they like. This is, needless to say, an utter misunderstanding of both our ideas and freedom in general. Simply put, if people impose themselves by force on others then "they will be the government" and "we will oppose them with force" for "if today we want to make a revolution against the government, it is not in order to submit ourselves supinely to new oppressors."

It should be remembered that just because the state monopolises or organises a (public) service, it does not mean that the abolition of the state means the abolition of what useful things it provided. For example, many states own and run the train network but the abolition of the state does not mean that there will no longer be any trains! In a free society management of the railways would be done by the rail workers themselves, in association with the community. The same applies to anti-social behaviour and so we find Kropotkin, for example, pointing to how "voluntary associations" would "substitute themselves for the State in all its functions," including "mutual protection" and "defence of the territory."

So, in simple terms, we would prevent murder and rape. We, the people. It's definitely worth reading the FAQ more as it also covers why rapes and murders occur, and why anarchism would dramatically reduce the incedence rate of those crimes.
