NP, you can I can agree on this--but you know full well that most of the population hasn't got an ounce of common sense among the lot of them. Sure as they let this fine young man graduate in his dress blues, some anti-war puke will want to prance across the stage in his pink lace anti-war costume, with "Bush lied, thousands died" in great big letters across the front and back of his costume. And if they don't let him, the school district will get sued. Bear in mind, this is a small town, and they don't have money to fight the ACLU lawsuit machine.
How long would this policy hold up if a Muslim wanted to wear a veil during the ceremony? My bet is that the useless educrats would be falling all over themselves to allow it.
