Also, one must not confuse the US with "the western world". I live in Germany, and I believe that you could be a dissident here w/o censorship. I also believe this is true for most other European countries.
My original point was that the statement: > And what would happen if you managed to actually start something that had a real chance at getting people in front of a judge and behind bars, that we can just guess at, since nobody has done it before.
Is simply not true. Mentioned Mr. Snowden as an example -- but there are more, like the huge leak of the panama papers.
I'm less familiar with Germany, but I'm willing to bet that while people in principle can say whatever they want (with some exceptions), there are other, less visible forms of repression and/or means of neutralizing those opinions. That they are less overt than in China doesn't mean they are not there.
Just don't say "The Nazis are great and I really wish they were back in power." That'll get you straight-up jailed under section 86a of Strafgesetzbuch, if I understand correctly. Everything else is on the table. ;)
The question is what happens if you break the rules. Are there rules on how to handle individuals who break rules? Do the ones who have the power also have to follow the same rules? What about those wo make the rules? Do they have to follow the rules? How is the process of rule-making, rule-checking and punishing separated?
I'm pretty sure that in most european countries this is pretty OK -- yes there are gaps, holes, and sometimes just plain unjust or unfair processes.
I'm also pretty damn sure that for some countries this is way off. China is IMNSHO one of them.
() There are still people wandering about who say this and similar things who are not in jail. You much more likely would get in trouble if you call someone a "goat-fucker" (google erdogan and jan böhmermann).
I thought he was claiming in the US it was possible to be a dissident without censorship or repression. My mistake!
