Just a day after the University of Notre Dame announced it would finally oblige long-denied requests to create a gay-straight alliance student group formally recognized by the university, the Catholic University of America again rejected a petition from its students to do the same. The CUAllies, who have been meeting unofficially since 2009 and have petitioned for formal recognition before, reported the news Friday via Facebook, saying Catholic will not recognize the group because of its “possibility of becoming an advocacy group.” Catholic officials declined to comment Monday afternoon.
