I don't agree. There were a bunch of university protests over Gaza (slapped down for stupid reasons by university administrators under pressure from government), and, really, they just made noise, but they got a lot of people to notice, including myself. And to ask ourselves, what do I think about this?
If you are expecting protests to force someone's hand, that isn't protest or protected political speech, that's coercion. Some forms of that are legal (e.g., strikes), but there are pretty sharply defined limits.
That's a good point, but the Gaza protesters would of course counter that they were slapped down (for stupid reasons) and the war in Gaza (which is illegal and genocidal, though initially provoked by Hamas) continues to be supported. So their protest, while not useless, wasn't effective in bringing change.
