Two branches of the City University of New York system -- Kingsborough and Baruch --
have apparently canceled Israeli Independence Day events sponsored by local Hillel chapters, citing security risks. In the case of Baruch, administrators reportedly offered alternative venues to the Hillel chapter (which were declined), at Kingsborough, by contrast, the administration reportedly refused to make any arrangements to enable the event to go forward.
CUNY is a public university, so this raises the usual First Amendment problems. While every case is different, there are some clear overlaps between this case (in particular, the citation to "security" concerns) and the cancellation of pro-Palestinian speakers and events justified on similar logic (for example, at USC). This, of course, represents a golden opportunity for people to lob dueling hypocrisy charges at one another ("You were aghast when this happened at USC, but I don't hear you complaining now!" "Yeah, well you were apologizing for this when it happened at USC, but you're aghast now!"). I'm sure that will be a grand old time for everyone.
I do want to make one note on the relative coverage and penetration of this story compared to other free speech debacles related to Israel and Palestine on campus. I haven't seen this story covered outside of the Jewish press. That doesn't mean it won't be later, and I'm not generally a fan of the "...but you'll never see this reported in the mainstream media!" genre of commentary. In part, that's because I think there's massive selection bias in what we claim is over- or under-covered; in part, it's because I think virtually everyone massively overestimates how many stories break through to mass public consciousness at all. In reality, I think different stories gain traction in different media domains, such that a story which might tear through one sort of social or ideological circle might make barely a ripple in another.
That said, in many of the circles I reside in, there is essentially no knowledge that there are any cases of academic censorship of "pro-Israel" voices on campus at all. To be clear, I'm not saying that there are not numerous cases of academic freedom violations targeting pro-Palestinian speakers -- there are a slew of them. But the notion that this is a Palestine exception to academic freedom, rather than something which unfortunately happens in a host of other cases and contexts (including, in the right-slash-wrong environments, to pro-Israel speakers), speaks less to the reality of academic freedom and more to an epistemology of which cases get attention and which don't. There are many academics for whom the Steven Salaitas are known, while the Melissa Landas are not. In other domains and registers, there are different gaps.
Ultimately, it's a variant on "they would say it about Jews, they'd say it about other groups too." The claims of injustice are not wrong, but the claims of uniqueness very often are. How many times have we heard variations on "can you imagine if there was a mob of people harassing and making racist remarks towards any other minority group -- how would universities respond to that?" (As we saw at UCLA, the answer apparently is "they'd sit back and let said mob kick the crap out of their targets"). And at the same time, we've also heard plenty of iterations of "if a university dared cancel a pro-Israel event, it'd be on the front-page of every newspaper for the next month" (so far, no headlines).
So I'll all say is that, if you're of the bent that there's no meaningful suppression of pro-Israel speech in campus environments, and your informational ecosystem (other than me, I guess) didn't alert you to this cancellation at CUNY, you should consider how the former belief might be correlated with the latter lacuna. Other people might have different gaps, and they should contemplate what generates them as well.
