The principal of Tallahassee Classical School was forced to resign this week after sixth-grade art students were shown images of Michelangelo’s David and parents complained. Yes, that David. No, I am not making this up. According to an interview with the school board chair by Slate’s Dan Kois, the principal of the charter school was supposed to send out a letter from the art teacher alerting parents that the nude statue would be shown. I can’t stop thinking about what this warning letter might have said.
