Not true my friend. Libertarians are one of two things.
They're Statists who think they believe in a limited state and voluntaryism, in which case they're fooling themselves because there can be no such thing. As soon as you give a political body power, it will seize that opportunity to increase its power, and will increasingly abuse its power at the expense of your individual liberty.
Or they're anarchists who haven't yet put two and two together and realized that it's an all or nothing game. You can't be a Statist and an anarchist. They're mutually exclusive. And if you're truly an anarchist, it would be a violation of your principles to participate in the affairs of the State.
I wouldn't participate in the affairs of the state, i dropped that religion a while ago.
It probably would have been clearer to say that voluntaryism is synonymous with libertarianism - absent the influence of the state. Almost all principles/codes of conduct and property rights/rules transfer directly between each other. Hope that clears it up.
