A libertarian is someone who wants to take America back to the way it was run in the 1800s, regardless of how much the world has changed since then. Libertarians also have mean hard-ons for unregulated capitalism, believing that the "Invisible Hand" will erase poverty and create a utopia instead of what ACTUALLY happens when you let companies do whatever they want, which is:
-Children working in factories and mines
-Workplaces where death is likely
-Low, low wages
-Shit in your food (Read Upton Sinclair's "The Jungle")
-Even more extreme corporate corruption and political pawns than we have now.
-Getting the living fuck stomped out of you by company-hired goons for trying to organize a union (Battle of the Overpass)
"God I've got such a mean hard-on for capitalism!" *fapfapfapfapfap*
