Whenever “discourse” like this comes up I am reminded of a specific clip of Kwame Ture. In it some white lib tries to catch him out with some bs gotcha about leftwing or liberatory violence I don’t remember exactly. Ture responds along the lines of:

If you were a slave would you not strike a blow to kill your master and gain your freedom?

The guy is visibly embarrassed. Which always makes me think that most of these people know (at least deep down) that liberatory and oppressive violence are fundamentally different but they also realise they are part of the oppressors so to accept this is to accept that violence against them can be justified. Which is a scary thought.
