Details, from RNS:
After political outcry and personal threats, an Italian priest has replaced a Christmas Nativity scene that critics said depicted Mary, the mother of Jesus, with a Muslim body covering. The Rev. Franco Corbo, a 76-year-old pastor from the southern town of Potenza, was the subject of a nationwide backlash on TV and social media and received hundreds of abusive telephone calls at his parish as a result of his Nativity scene.
