Hearing other perspectives doesn't make somebody an enlightened centrist, it makes them knowledgeable and more aware. There's nothing wrong with gathering perspective and context before judging something, that's what people should always do. It's a sign of wisdom, not ignorance. You would have to be mind numbingly ignorant to actually believe that being in echo chambers is a good thing.

In order to see the balance in all things I must accept the holocaust deniers and the Holocaust believers.
