The quoted tweet mentions "videos", and is actually a thread of multiple posts. You have to be signed in to see them, or use a nitter proxy[1]. If you look at those videos, it's clear that they're not calling the protesters "terrorists" for merely protesting, they're calling them "terrorists" for engaging in behavior such as intimidating jewish students or praising the October 7th attacks. It's slightly misleading to round that off to "protesting Israel's actions in Gaza".
