It’s not often that Supreme Court justices weigh in on undergraduate housing arrangements. But when the president of Catholic University announced plans to end co-ed dorms in the name of promoting chastity, none other than Antonin Scalia offered a thumbs up. “Our educational establishment these days, while so tolerant of and even insistent upon diversity in all other aspects of life seems bent on eliminating diversity of moral judgment—particularly moral judgment based on religious views,” he declared. Scalia must have been pleased this fall as the school successfully fended off legal challenges against the policy filed by George Washington University professor John Banzhaf. On the other hand, any conservative might have been less pleased to read a lengthy Inside Higher Ed report on the dorm policy, which noted that supporters and opponents agreed that undergraduate sex would remain a popular activity no matter what the dorm rules were.
