People who are afraid of the "left authoritarians" seem to think that you can just sum up human history and cherry pick some great "left-branded" authoritarian and equate that to todays.
You're arguing that the people kidnapping people without due process and zero consequences, masked police, are equal to some arbitrary "leftist" in some time that's not relevant to todays political climate.
It truly is bizarre how mental gymnasts survive in this logical incapacity.
Sorry but I can't take this seriously. I've given more than enough contemporary examples, if you want to dismiss the whole of it and pretend nothing makes sense, that's a choice and I can't help you.
All your examples were social movements that did nothing or virtue signaling from massive corporations owned by right wing billionaires.
