Libertarians support proportional representation

The state gives people freedom from crime so the state is a liberal and Libertarian concept. And if to have a state requires that we have a democratic state then democracy is a liberal concept. So then it is a contradiction for a Libertarian to reject democracy... and by extension proportional representation. Libertarians support pr because without the state there is no freedom (from crime) and without democracy there is tyranny. Any lack of democracy is tyranny so first-past-the-post is tyranny even though it is not as bad as outright dictatorship. Proportional representation is a Libertarian concept and Libertarians support pr.
