Tell that to right-wing media. They focus 100% of the story on the bad actors, and like it or not, half of our government reads that news exclusively. Extremists are a cancer to any cause. The message to share with protesters is to have zero tolerance for extreme behavior, and immediately call out bad actors that show up at their demonstrations, for the good of their cause. Especially now that being a bystander can get you charged.
You want the news to read, “Protesters criticize and eject demonstrator calling for killing Jews from pro-Palestine rally.”
