...for some time, I've been mulling over a gedanken experiment in which you take a group of diehard libertarians and a group of commie pinko-types, and set each onto identical islands to populate in their own utopian fashion. I hypothesize that when you returned in 50 years, if they hadn't self-destructed, they'd more than likely look quite similar. Humans always seem to be battling the twin evils of extreme liberty and security, not matter which ideology holds sway at the moment.
