Your proposition is interesting but there are some little problems and one big problem.
Little ones, not a lot of time right now and some heavy preparations on my part would be necessary.
The big one, We need to come to an agreement on the Definition of Marxism.
While that may be one quote among many it clearly shows an acceptance of authoritarian measures ,perhaps only sanctioned to achieve a goal, but not a condemnation of Authoritarianism.
I will look into the context if you can give me a quote where Marx condemns Authoritarianism as method in revolution or governance not of course a condemnation of his opponents.
Saying context matters and leaving it at that makes me feel like you will only answer my points dismissively a counter quote is the least you could do.
I will go into definitions and the how they are a problem in todays political discourse in my response to your other reply.
