> I would say that in a society like that, there is more amiss than simply a lack of free speech.

Every society (and community) has norms which are acceptable, and those which are not. If a person decides to not live according to those norms they're an outcast and will be dealt with as such. The society is like a living organism which will protect its norms in order to survive akin to an auto immune system. Because of these principles every society lives within its own bubble, too.

I suppose Von Trier's Dogville touches upon the subject, but there's countless examples available from Swartz to Snowden. If someone has another (or better, more accurate) example I'm interested hearing yours.
