Violence erupted at the University of California, Los Angeles after pro-Israeli counter-demonstrators attacked a pro-Palestinian campus encampment. Bubbling tensions on the campus boiled over following the alleged breach of a "buffer zone" between the rival groups.
Nonviolent protest works when the violence against the nonviolent becomes the impetus for change. That whole Jesus taking the beating to point out the problems in the system has a long history whether you believe in religion on not. Probably why we still talk about non-violent protesters like Gandhi or MLK, too.
That’s not to say that violence doesn’t have its place, like the French Revolution. But that’s the shortcut. You forcefully break the system and rebuild it right now, rather than the long game of changing the system from within.
Checking out the author, he seems much more French Revolution type (even though being an anarchist really puts him at odds with any resulting government), looks like he’s spent a bit of time in jail for some protests, none of them violent.
