Everyone thinks that the other side of an issue is spreading disinformation. It's such a vague and ridiculous assertion to assume that any person, organization, entity, or any one side has the truth, the whole truth and nothing but the truth. Freedom of speech is a prerequisite for a society to arrive at anything close to resembling truth, because no one has a monopoly on truth. No one can adjudicate it. Ideas must compete. Perspectives must be entertained. Right now, in this very moment and in all moments in history, there are mainstream ideas that are thought to be absolute truths which are brazenly false.

Debate is how you get educated. Nothing else can suffice.
