You scored 68% Personal Liberty and 66% Economic Liberty!
A libertarian believes in little to moderate government intervention on both personal and economic matters. They generally believe in a government that is small and limited to the extent of protecting people's liberty. They tend to be opposed to war, police powers, victimless crimes, foreign intervention and what they consider to be a welfare state. They support both property rights and self-ownership. More moderate libertarians may use a more utilitarian or gradualist approach, while the more heavily minimalist libertarians allow less room for compromise in a direction that they consider to be away from liberty. Libertarians generally support capitalism as an economic system. Libertarian thought tends to be individualist in nature.
