I guess the simple explanation is that everyone MUST think for themselves. Which is why the Trolls are here, it is their job to ensure you don't wander too far away from Politburo approved Pablum..
"The Matrix is a system, Neo, and that system is our enemy. When you are inside, you look around, what do you see? Businessmen, teachers, lawyers, carpenters, the very minds we are trying to save. Until we do, these people are part of that system and that makes them our enemies. You have to understand that most of these people are not ready to be unplugged and many are so hopelessly dependent on the system, they will fight to protect it. The Matrix is everywhere. It is all around us. Even in this very room. You can see it when you look out your window or when you turn on your television. You can feel it when you go to work, when you go to church, when you pay your taxes. It is the world that has been pulled over your eyes to blind you from the truth."
-- Morpheus, "The Matrix"
