Columbia University has “temporarily” banished its most distinguished pro-Israel Jewish professor — Shai Davidai — from campus property, a severe disciplinary sanction which prevents him from attending university functions and accessing his office.

Speaking to The Algemeiner on Wednesday morning, Davidai denounced the action as retaliation for his much publicized advocacy of Jewish civil rights, unabashed support for Zionism, and condemnations of student and faculty calls for continued acts of terrorism against Israel and other Western countries. He has, he noted, been targeted by the university before. Last semester, it launched an investigation of his conduct following spurious accusations that his denouncing terrorism amounted to anti-Muslim bigotry.

Now, the university has allegedly found cause to discipline Davidai under a microscope, punishing him for an exchange of words which took place during dueling demonstrations marking the one-year anniversary of Hamas’s Oct. 7 massacre across southern Israel. According to Davidai’s own social media account, as swarms of pro-Hamas students bellowed slogans demanding violence against Israelis, the Columbia professor filmed himself reproaching the university’s chief operating officer, Cas Holloway, for permitting anti-Israel activists to hold a celebration of the terror attack — in which Hamas-led Palestinian terrorists murdered Jewish children, sexually assaulted Jewish women and men, and kidnapped over 200 hostages during their rampage.
