When Penzel spoke June 2 last year at Radboud University in Nijmegen, Netherlands, protesters broke windows, threatened him with bodily harm, and denied Hamas’s atrocities, screaming “lies,” and insisting there were no women raped. Harry Pettit, assistant professor of geography at Radboud, posted on social media that Penzel was a “terrorist,” said Israel was committing a “holocaust,” and that the school “should refuse to normalize platforming Zionists.”
