They were not massive. There were some, but they were fairly small in comparison to things like Occupy Wallstreet or even George Floyd. They were tiny in comparison to the number we're seeing for Gaza (especially at universities) because by and large most people supported what happened after 9/11 because they felt like America had been attacked and even excessive retaliation was fair game.
As for the fad, these protests are not made up solely of Palestinians. Palestinians make up something like 0.05% of the US population. They're involved of course, but they do not make up more than a token amount of the protestors. Calling adoption of kids from Africa sounds dumb too, but it absolutely was a fad. Americans are quite good at following stupid fads. This is absolutely a fad issue, and it too will fade into the background noise in less than a year when something else happens to draw the attention of the populace. The US will go on sending aid, Palestinians will never get a country, and both Israel and Hamas will continue fighting and civilians will die.
You're right about one thing though, se should push the government to do more on ALL those subjects. My question is if this isn't the biggest issue, why are we pushing to get it more coverage than other issues? Why does this particular issue deserve so much attention and support compared to other issues?

You're the one that needs a wakeup call if you think that the Democrats challenging RFK Jr. is unacceptable but what the Republicans are doing is fine.
