That's orthogonal to what I said, which is that freedom of speech can be easily permitted if speech doesn't really have any consequences, e.g. if there aren't actually any popular movements that speech could stir up.
That's so whether those movements are against some right wing regime or some left wing regime (or generally left/right government establishment).
That said, I do believe that socialism is better than liberalism.
At least the former is an actual form of government, with a legacy and original thinkers going back to centuries, and practiced e.g. in Sweden, Denmark, Switcherland, Canada etc. for half a century or so (and with policies adopted all over the world in some form or another).
The latter is just some abstract doctrines based on protestant ideas that time after time lead to bad results (corporatism, every man for himself, broken social contracts, etc.) where it's overly practiced. Even U.S. itself in fact has been much more socialist than liberal for the most part.
Except if you mean "really existing socialism" a la Eastern Bloc, which where mostly post-war "colonies" of USSR.
