I completely agree that using the word “Kristallnacht” in the context of expressing anti-Zionist sentiments is indefensible and an antisemitic slur.
However, reading your [ETA: No, Jackmannii’s; sorry, this reply should have been to Jackmannii rather than Babale.] linked cite has also made me a bit more doubtful about the allegedly antisemitic nature of the attack on the Hillel building:
Now, asking somebody in a Hillel building if they are Jewish when that has no relevance whatever to any aspect of the situation is undoubtedly gratuitously rude and intrinsically antisemitic, true.
However, a bunch of rowdy people throwing pebbles at the window of one of their friends in his Hillel residence because they want him to come out and hang with them is a very far cry from a violent antisemitic mob trying to break Hillel’s windows.
I can’t judge from the incident report quotes exactly what it was that happened, but I am not as confident as I was that the window-pelting part was obviously an antisemitic attack.
