During the Chinese Cultural Revolution the Red Guards lynched their professors (and many others).
The neo-Red Guards need to be confronted and beaten on the intellectual battlefield. Flat out. They are bullies and bullies only know one thing. Fundamentally the PC brigades are collectivist wimps. They run in packs because that is the only way they can sustain their cult. Individually they know their whole worldview falls apart. They must reinforce their delusions of victimhood en masse.
