Snowden is a Libertarian. There are no Libertarian heroes. Libertarianism is an ideology devoid of moral force and has adherents who are mostly comprised of asberger's and autistics whose sole concern is the misguided application of order on a chaotic universe. That's not a slam, but an accurate description - those types of people enjoy the wishful thinking of simple and clean systems in a world filled with grey and ambiguity. It explains why most of them become computer scientists or enter technical fields and avoid biology or literature.
