More than a week after Charlie Kirk’s assassination, the shock waves are still rolling through higher education. Kirk’s murder, on a college campus, in the act of open debate, was committed by a killer who reportedly believed that “Some hate can’t be negotiated out.” Although the assassin was a college dropout, his apparent logic was very familiar on campus: some ideas are just “hate,” and the normal rules don’t apply. Hate has no home here, as the saying goes.
