Speech has probably never been freer in the world than it is today: Multiple venues – especially social media – allow people’s perspectives to take flight fluently, globally, and frequently. The culture of free speech is also under steady and ever more sophisticated assaults, perhaps because its ubiquity is threatening to any person or institution that holds an opposing viewpoint. The very thing that makes speech so free right now – ease of motion – is, perhaps, what also makes it more threatening.
