I believe that's the case here. The top end of the leftist food chain knows they're fascists and they want ultimate, unrestrained power and control. The bottom end of the leftist food chain are the un-informed and ill-informed masses of useful idiots who believe what they've been told - that they are the good guys and we are the bad guys. (all evidence to the contrary) In between are the over-educated elitists who have actually deluded themselves into thinking they know best and it really would be to everyone else's benefit if they could run things the way they want to.
It is this third group - the middle tier - that is the most dangerous. Sure the fascists at the top are enemies. They always will be but fortunately there aren't that many of them and they don't like to get their hands dirty. The sheeple at the bottom would recoil at the thought of loading us into cattle cars to be forcefully interred at "truth and reconciliation" camps. So to would have the good people of 1930s Germany - until it was too late then they had to else they would be next. That middle group though. They will proudly, joyfully don their brown shirts, or antifa or blm or Che shirts, raise their fist in salute and start marching us off. All the while they'll be convinced they're doing it for the good of everyone including us.
So when a couple of leftist loudmouths start spewing notions of arrests and commissions, we should take notice. There's a pretty good chance they're serious about it, and they have a lot of their people kool-aide saturated enough to go along with them.
Very, very well put.
