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.
It seems like you’re having a difficult time understanding this, maybe I can help. If another group of people showed up, and they had signs, and maybe bullhorns, and they started protesting the opposite of what the original people were protesting, they would be counter-protesting. Some heckling could even be involved.
When they show up wearing masks and wielding baseball bats, they are not counter-protestors. They are violent criminals. They did not show up to protest. They showed up to insight violence.
