Whether or not one agrees with a person's viewpoint (whether based upon religion or not) concerning nudity, it is the parent who must have the decision of what is right and appropriate for her/his child concerning sexuality. That seems to have been the problem with the teacher--his lack of action concerning his responsibility to the parents. I have dealt with parents who are extremely selective about what their children consume whether in pictorial or written form, and even to the diet of food, and I have others who seem to have no view that would require adjustment from the school's view point. In the same way we support students with different learning abilities, we need to support students who come from different learning tolerances. It is a matter of considering the parents and the manner in which they choose to raise their children, in my humble opinion.
