while all attempts at communism has proven to be endemically-afflicted with an authoritarian existence that would have me exterminated as "useless".

This is completely false. Socialist states aren't the ones doing eugenics and killing the disabled. That's fascist and liberal states doing it (I'm sure you see how MAiD is sinister). Socialist states, while not always prioritizing the issue of disability, have sought to help the disabled so that they can help in the ways they can rather than waste away in a hovel as they were left to in feudal society.
