Religious Art and Public School

My thoughts- Public schooled high schoolers were made to sign an agreement in art class not to have religious art. That in itself is ridiculous. First of all minors should not be made to sign any thing of the sort. Secondly just because someone signs a sheet of paper doesn't mean that their rights should be taken away. I do not think they were fully advised either.

Where does the art teacher think art originated? Some of not most of historical art has some sort of religious background. Michaelangelo's David to Bernini's Rape of Persephone.
