I mean the ruling class is not only interested in keeping the peace. Sometimes street violence serves their interests, and I think his purpose is less about preventing the left from punching chuds and more about steering the left away from threatening ideology, and thus in turn threatening praxis.

And I'm sorry but I'm not interested in a nuanced take about someone who works for an NED-funded rag and tells the "radical left" to hate all of the US's adversaries and do ineffective decentralized/horizontal organization.
