The Non Aggression Principle or No Coercion Principle says no initiating of force is ever legitimate which is counter The Word of God. The Bible teaches the State is God's Sword for punishing evil and rewarding the good. It is not in His Word that only retaliatory force is good.
You do not wait if you have justification to use force first. You do not wait for someone to setup a Pagan alter and sacrifice a person to use force to stop it from happening by banning Satanic Rituals. Those that want to abolish the slavery of the sex industry do not wait for someone to cry out for help. There is no initiation of force in the sexual immorality that should be included in our legislation.
If I need to support legalizing anything and everything to be a Voluntaryist than I am still a minarchist.
