As college campuses shut down for winter break, the Maoist insanity that gripped American higher education this fall hit a new high-water mark. At Harvard, little laminated posters began appearing in the student dining halls with instructions on how students should discuss sensitive political topics with the rubes back home over the holidays. For example, what if, over Kwanzaa-eve dinner, a family member says, “We shouldn’t let anyone in the U.S. from Syria. We can’t guarantee that terrorists won’t infiltrate the ranks of the refugees.” Well, the poster instructed students to respond, “Racial justice includes welcoming Syrian refugees.”
