left-wing extremism

It's not all positive. I mean, look at all the 'socialist' revolutions in autocratic nations. Those were built from the fundaments of the Western left. The main thing these days is the way in which the right has co-opted the language of the left in order to advance their agendas. That's what I think S03E01 of the Dakumentary demonstrates: Luxon and Seymour don't sound like your traditional demagogue.
