Libertarians in my experience are those particular conservatives that are unable to form social bonds with other humans.
I’ll be honest, most of the Libertarians I’ve met have a twinge of morality. So they call themselves Libertarians so they can support Republicans while not feeling guilty about it (since they disagree with both sides).
They also do tend to be the cliche inexperienced college kid of the Republican party that is overconfident in their niche political views.
