It is important to remember that statist who do not understand liberty are victims and we must remain patient and understanding of them (even though they are unwittingly advocating for aggression against you). They did not choose to be a statist, they were thoroughly indoctrinated from before they could even walk, at least I was and everyone else I know.
It may take days, weeks, months or even years for an indoctrinated subject to be able to see the truth but if they are exposed to it then its only a matter of time before their indoctrination is rendered useless and then they too will be advocates of liberty. In short, be a symbol of truth and liberty, be patient, remain persistent, and accept the hardships that we are guaranteed to endure in the animating contest for freedom.
