Yes, the the SDS and other antiwar students harassed Pusey and forced him to resign. (Pusey did a lot to boost Lutherans at Harvard—I was a Lutheran back in the day, and am now Orthodox.)
The leftists before recent days were NOT antisemitic. Many were Jewish, and some of them were unfortunately anti-Christian.
Nowadays, with “DEI”, Harvard is full of antisemites who are also anti-Christian. Nowadays, Jews and Christians need to ally ourselves against muslim extremists and feckless Gen Z antisemites, for our own protection!!
Being anti-Christian has more to do with being a leftist than being descended from the tribe of Judah. Leftism is based on atheism, so any leftists who are descended from Judah are self haters.
