So, what makes a Libertarian?

I don't know how they get the grants for stupid stuff like this, but scientists think that those who tend to be squeamish about "gross" stuff, like bugs, blood, gore, and dirt are far more likely to be conservatives. They suggest that conservatives are likely to have clean, well organized workspaces, as opposed to the colorful, stylish, and cluttered workspaces favored by liberals. They suggest that there's a biological element to political makeup.

I sincerely doubt that. I think that, rather than nature, it's a case of nurture forming the politics. I think that children either follow in their parents' footsteps or rebel so hard that they go in the opposite direction.

In any case, how would they explain Libertarianism? Y'know, the people who strongly and sincerely believe that the government should get out of the social safety net business, and stick to the limits set by the Constitution of the United States? The people who truly don't care what their neighbors think or do, so long as they're left alone?
