There are two types of people who call themselves libertarians. The first are Constitutional conservatives. The second group are liberals who just don't like paying taxes. Other than on some economic issues, they don't have much in common.
Bull. I am tired of libertarians getting free pass. For instance I find it appalling that most Libertarians are Free Traders and NOTHING in the US Constitution allows for duty free trade across international borders. In fact the opposite is the truth. They have been gas lighting us for decades on this. As such IMO Libertarian are as big a threat to freedom as liberals. Most of them are atheists, think military spending is a waste and want a border free world. Of course there are exceptions but they are rare. On these issues they intersect with their liberal cousins.
