Religion has priority over culture because the general rule is that a "heaven or hell" issue is more important than a social ostracization (sp?) cultural issue. Kilts are not universal in Scottish culture so it becomes a weak argument (made stronger, by the way, James, with the decision to kilt the new Scottish regiment).

My letter to the principal:
I understand that you've recieved a number of emails regarding the barring of Nathan for wearing a kilt. Let me be among the number who believe that you have erred. If the newspaper article is correct, then there was no reason to bar him. I recognize the article may have left some details out. However, the article seems to indicate that he was wearing it respectfully and traditionally.
I was born in Scotland, wear a kilt, and cannot fathom how it can be such a distraction so as to ban Nathan. I wore one as a child, at my wedding, at my Canadian citizenship and many other times. There are marines in Iraq wearing kilts. Yes, it would be a distraction if the rest of the student body is undisciplined but my experience is that is not the case when it comes to a kilt. In any case, you have blamed the victim and owe him an apology. The article mentioned the Grad ceremony, it would be appropriate to okay that event.
