The beauty of any conspiracy theory is that because it can't be proved, that just makes it more 'real.' It's not a question of believing or not believing, really; it's more a question of just accepting a series of probabilities that lead to an undeniable conclusion.
The 'conspiracy theorist' is no longer a crazy person with a tinfoil hat, but they are the Edward Snowdens and the WikiLeaks that bring down major institutions and are the catalysts for social change.
