Last week Dr. Hatem Bazian, a lecturer at the University of California, Berkeley, became subject to intense criticism and calls for his dismissal after it came to light that months earlier he had retweeted an anti-Semitic meme. The incident follows years of false accusations of anti-Semitism and outlandish claims. Dr. Rabab Abdulhadi, a professor at the nearby San Francisco State University, explained in emails this week to her colleagues and the UC Berkeley Chancellor that Bazian is being victimized by a campaign: “I urge you to strong reject this bullying and smear campaign. I call on you to publicly defend Dr. Bazian against this witch hunt.”
