The University of Waterloo is once again preparing for protesters who might try to shut down a speech, reports The Waterloo Record. The university says it will protect 80-year-old Charles Rice with extra police when the Catholic professor emeritus gives the annual Pascal Lecture on Christianity next Tuesday on the topic of morality, enlightenment and The Natural Law. The former professor is opposed to same-sex marriages and abortion, which has caused some students to oppose the lecture. Protesters successfully shut down a talk by writer Christie Blatchford when she first tried to speak to an audience of 27 people at the university about her book on the Six Nations occupation of Caledonia in November 2010. Her rescheduled speech drew a crowd of 300.
