DON’T MESS WITH MICHELANGELO: A school board in Florida made news last week after forcing out a principal for showing Michelangelo’s David to her art students — after complaints from parents that it was “pornography.” On Saturday, the mayor of Florence, Dario Nardella, shot back at the “ridiculous” decision: “I will personally invite the teacher to Florence to give her a recognition on behalf of the city,” Nardella tweeted. “Art is civilization and those who teach it deserve respect.”
