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.
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.
