I know a number of places where you were rewarded for "rightthink" and could be imprisoned or murdered for "wrongthink". Most of them had been countries having "People's Democratic" or "Socialist" or something in that vein in their names. I'm sure that's also a pure coincidence having nothing to do with those systems. Though, to be fair, modern followers of those doctrines made a serious headway to implementing the same approach in countries which don't have such words in their names and even considered "capitalist", so I assume in a short while you'd have another excellent argument - that freedom of speech also wasn't particularly suppressed by totalitarian (which is, all of them) socialist governments, it's just something totally separate. Which always happens under socialism, but that's just a coincidence, and it was a wrong socialism anyway, under the right one it won't happen.
