Nativity crib offends Muslims, rules priest

A priest in northern Italy has caused an uproar by announcing that there would be no Christmas crib in the local cemetery this year so that Muslims and atheists would not be offended.
“A corner of the cemetery is reserved for Muslim graves,” Father Sante Braggiè, from Cremona in Lombardy, said last week. “A crib could be seen as a lack of respect for the faithful of other religions, offend the sensibilities of Muslims, Indians and even atheists.”
