I may not be speaking for every individual whom considers themselves libertarian when I say this; Libertarian-ism is synonymous to Constitutionalist, here in the USA, so with that in mind I reference you to the U.S Constitution. Specifically, the 10th Amendment and the power it gives you the individual withing your state to make the laws of your concern so as long as they do not infringe on civil liberties; each state is a democracy of its own. In other words stop generalizing Libertarian-ism in a negative way, for it would only reflect on the failure to perceive the power the people have. I care for food regulations, environmental laws, and even social programs, just not the one's ran by the Federal Government.

Don't judge each day by the harvest you reap but by the seeds that you plant. --Robert Louis Stevenson
