You can support a two state solution, pre 67 borders, or even think Israel shouldn't exist at all without advocating for the murder of random Jews by Palestinian terrorist groups.
This is the rooting for the underdog, "punching up" mindset taken to the furthest extreme. In their world if you're "marginalized" then nothing you do can be wrong and if you're the designated "oppressor" than nothing cruel anyone does to you can be undeserved. These people think real life conflicts are like Star Wars with a designated light and dark side.
How many of the people crying about this have spent the last decade complaining about the lack of free speech on campus? Seems like a near 1:1 especially with, say, Bari Weiss types.
I'm not calling for anyone to be expelled from school or face academic discipline for this. We just can and should call it out for what it is.
And on the other hand how many of the people doing and defending this have called for campuses to be inclusive safe spaces for all people and advocated for censorship to attain that goal. If these were right wing student groups talking about black people like this we all know they'd get immediately shut down.
