I know what the free market is, but I don't believe in this pseudo-free market we live in. A true free market capitalist society is one where the state and corporation do not exist, nor nations. What we have now is state-capitalism, fascism, or corporatism.
The political system is a construct of the economic system, as much as it is the ideological beliefs of a nation's members i.e. a judge is employed by the government, not a private company - though the government in turn is influenced heavily by economic or corporate interests. Though communists make no distinction between the state and corporation, arguing both are products or creations of capitalism.
It is curious you think that the state and corporation, can exist in a real free market economy, when state and corporate monopolies are the anti-thesis of a free market system i.e. a free market economy must exist in form of private contracts and small and medium size business to be a real free market.
It is ignorant to defend 'capitalism', when the 'free market capitalism' you are defending is a sham, as it is just a wolf in sheep's clothing.
Better to be a democratic-socialist or a 'liberal' as you term it, if it means not drinking the kool-aid that is neo-liberalism and the false free market.
