It doesn’t make a ton of sense for non-students to protest at a university. What are impeding? Students and professors who probably already side with you from going to class?
Universities are for meeting, rallying and handing out pamphlets. Actually protesting there will have no effect on the general populace of aside from creating a very strong suspicion of straw man tactics.
Creating a “you’re either Pro Israel or Pro genocide argument” with the liberal youth is good way to get many of them to either not vote or to not vote Biden. I strongly suspect that’s what’s happening here.
