Thanks! I've lately been giving more thought to us recognizing what I am calling the "right to NOT participate." A lot of people are pissed off that judges are ruining their school events on the account of objections of a small group of, or in many cases even just one student who seeks to ruin everything for everyone else.
From a legal perspective, there isn't really much we can do to fight such rulings, especially given the costs and time involved. So I think the alternative of a private graduation ceremony would be the most ideal one.
