The Problem with Ron Paul
The problem with Ron Paul is that his isolationism (discussed here) is annoyingly consistent. A standard liberal thinks “Yankees go home” is a legitimate slogan and “Mexicans go home” is bigotry. A standard conservative thinks the opposite. Ron Paul apparently thinks everybody can go home.
On the other hand, what if your ancestry is partly from one area and partly from another and you'll have to be dismembered to go home? That might explain the support Ron Paul has gotten from opponents of “race mixing.”
