Concerning a policy of 'free speech' on social media, presses, etc - the libertarian ideal is nice and all until you realize in reality there's a lot less time spend contending with enabling thoughtful alternative perspectives that eschew convention but preserve rigor, and lot more spent trying to stop people from convincing themselves the Earth is flat, or that Paul MacCartney died, was replaced by a lookalike, and the Beatles left clues to this in their albums.
