Btw who is to determine what is crime and what is not?
It's not who but what, that is if there is a victim.
Punishment is not a solution, it's vengeance and vengeance is evil.
A murderer has forfeited their right to live, it doesn't require a punishment, only a recognition that they have agreed that they don't believe the right to live is a right, therefore they are free to be killed so should someone chose that. Punishment won't resurrect the victim. Punishment is always vengeance and not restitution. What you want, I hope, is restitution, and in case there is no restitution you can go and hunt all the murderers you want because it's not a crime if they have forfeited their rights.
Socialism always requires a monopoly on force, and because of that it will force people. Libertarian socialists sounds very much like an oxymoron therefore.
I talked about using 'Vogelfreiheit' instead of prison in the article I linked you.
nope, you just define socialism as state communism. Look at the very definition of the word "social". It just acknowledges that we live in a society.
If you want me to get rid of the word I have to disappoint you, we Germans just associate completely different things with it and I don't want to be lumped up with capitalist nut-jobs like you :P
