So the protestors are tortured until they confess to bogus terrorism charges? Locked up under horrible conditions in labour camps in Alaska for years and decades? Do you risk imprisonment for merely saying to someone you thought you could trust (like, say, your children) that they should be allowed to protest? Because then, yeah, that kind of brutal oppression.

Of course there were some things generally done better in the USSR, thing is, you don't need a fucking socialist dictatorship for universal healthcare, social security or public education. Many, many capitalist countries offer all of them.
