Not only it is wrong from a historical point of view, but it also ignores current political conversations in which "Leftists/Communists" are used as a scare tactic.

Fair enough, i guess i also "fear" communism in a sense and believe that humanity must work to prevent ourselves from reaching such a state (at least the sort that is typical of it) but i don't think that's where much of the criticism on Lemmy stems from

I have a lot of criticisms, but I don't currently have the energy for a long debate. However, my main criticism is that Marxism is unnecessary as many good things have been achieved and can be achieved under a social democracy.

There's also the point on how Marxism is practically unachievable without collectivisation, which allows for the possibility of tyranny. Soft totalitarianism as i like to call it. It has gone wrong in the past and will probably continually do so.
