As a Pro-Palestine supporter myself, I can confidently say that this young man does NOT represent the views of 99.9% of Pro-Palestine supporters.
He is young, inexperienced, and was speaking (and most likely acting) in the heat of the moment. I know for a fact the Legitimate Pro-Palestine movement is NOT about murdering innocent (or guilty) people. The entire movement is founded on the belief that peace must be achieved in Palestine/Israel. I myself am a Pacifist, and I do NOT believe we should kill others simply because they have differing opinions or views.
Also, the notion that all Pro-Palestine protesters/activists are 'Pro-Hamas' or 'Anti-Semitic Communists' that is being peddled furiously by right-wing media and influencers would be laughable, was it not such a serious issue.
I hope that this comment has at least shed some light on the true nature of the Pro-Palestine movement. Thank you, have a great day.
