There is a similar discussion going on about online forums. What community standards need to be upheld when it comes to scams, online bullying, hate speech, disinformation, or sexually explicit images? There are very few people who believe that there should be no limitations at all. Instead the question is what counts as acceptable to the broader public, especially in forums that are accessible to children or teenagers.
Unfortunately, there are people who go to extremes with their censoring, banning ideas that go against their personal sense of ethics (usually only a small part) despite many people not sharing their views. In the case of my email argument, I feel that I might be getting lumped with that side as I am lobbying for stricter guidelines when it comes to student performances. Still, I want my students to feel safe in going to watch other student's events, and I want their parents to feel safe in allowing them to participate in the DDF program.
It's a delicate business, and I rushed in with my usually lack of subtlety. Still, I feel that it needed to be addressed openly rather than just whispered about. We all want what's best for our students, but we don't all agree as to what that might be.
