Regarding freedom of speech, Marx observed that there is no such thing as freedom of speech in class society.
I already replied to this and you are apparently ignoring Marx was speaking of a historical point in time. Not an on-going directive of state sponsored suppression of voices.
Socialism is necessarily still within class society, and ergo capitalists must be oppressed by the state, lest they overturn it. In communism, there can be actual freedom of speech, because by that point class has been eradicated. Marx fully aligns with my analysis of class society, this is part of the theory of the “dictatorship of the proletariat,” of the proletariat as the masters of society.
Again, Marx and others said the "dictatorship of the proletariat" temporary state to enact a change, not a permanent state of repression of the people. Marx and Engels said they recognize the need for "revolutionary Provisorium" a temporary, extralegal period following a revolution against the old ruling class. TEMPORARY.
The same applies to assembly and association. The working classes should be able to do so as a class. Capitalists should not be able to do so, nor should those that work against the interests of the working class.
This is so much worse than I'd imagined a take on Marx's work. This is a twisting of the words and ideas. I'm horrified that someone that identifies themselves so strongly as a socialist champions this dark version.
Earlier you said you identify as a tankie. I agree with you that you are, and you fully meet my definition of one too. I had always wondered where the strong support for authoritarianism came from from tankies. I have a much better understanding now. Its the narrow reading of steps needed to enact change twisted into a permanent state of revolution resulting in the permanent suspension of civil liberties leaving only enough room for a single group think lest the state come down for saying otherwise.
This has been a very enlightening conversation. I'm rattled by this and am concerned about how this authoritarian reading would influence otherwise progressive Marxian socialist implementations in the future. I do thank you for taking the time to talk to me and share you views, but frankly they're terrifying.
