>This all sounds good, but if I assert that the earth is flat on Facebook why shouldn't that simply be labelled false so others can avoid wasting their time trying to refute a ridiculous assertion? The particulars aren't the issue and never have been. The issue is, there's no "authority" you can trust to decide for you what is and isn't true. The particulars are of what's being discussed is a red herring. Facebook, youtube, twitter, and reddit, all think they know better and you should trust them. It would be far less alarming if they didn't all agree with each other all the time. There's no significant political dissent between them. The present a single face. Aka fascism when they agree with the government, which they currently do.
