April 24, 1968 (pdf) "300 Protesting Columbia Students Barricade Office of College Dean." I recall reading about this at the time, in high school. There was a lot going on in 1968. The Dems weren't smart about the Vietnam protestors, and it arguably hurt them in the November election that year, when Nixon got elected. (George Wallace took some southern states, 3d party, too.)
Violent repression of anti-war protestors at the DNC Convention that summer in Chicago didn't help. They had contempt for the protesters & didn't read the room. 18 year olds couldn’t vote yet in 1968, but that changed in 1971.
I wish Biden had visited a mosque back in October, but he didn’t. (Dubya got that one right after 9/11.) I wish Biden hadn’t equated “Hamas”& “Palestinian” either, but he did. For an empathetic guy, he’s got a huge blind spot when it comes to the humanity of Palestinians.
History doesn’t repeat itself, but it rhymes. Fingers crossed that the Dems start listening to the kids on this one. There’s plenty of reason to object to imposed mass starvation & aid trucks being turned away if they have sleeping bags (zippers!!), nail clippers (weapons!), water purification tablets &c. Calling those objections “anti-semitism” doesn’t help either. My personal opinion is that there’s been more than enough vengeance for Oct 7.
An opinion piece in the Gray Lady, just posted a couple hours ago, suggests that Columbia handled protests against apartheid in the 1980s better than they did back in 1968. Or are doing now.
