Of course, and as it stands foreign nationals on Visa's in the US don't have the same rights as citizens. Not that they shouldn't have some degree of free speech, but they can also be scrutinized and deported for advocating for violence and terrorism.
That scrutiny is a waste of federal resources since you're basically extending the notion of advocating violence to supporting any side in any war - perhaps meta should just go ahead and remove all posts on both sides.
No I’m not, but in case you missed the news several of the pro-Palestinian protests were violent or openly called for violence. Similarly with the posts in question.
