Worse than stateism victimless crimes? Seriously? Say you initiate aggression and slap me when I have not done anything that constitutes aggression towards you, and I proceed to hand you an ass whooping, how do I know you won't come back with a knife or a gun?
Now I'm not saying that I would always or automatically resort to lethal force. That would only happen in cases where I felt the threat of escalation by the aggressor was a real possibility, but under THOSE CIRCUMSTANCES I maintain that I am within my rights to assure that I am not the victim of further aggressions.
