What is the matter with these idiots. Don't they have anything better to do with their time and the taxpayer's money? Is the NISD so flush with cash that they can afford all the legal fees?
I am amazed that a school would concern itself with such trivialities. That they can justify their actions, I have no doubt, but I suspect that these people just enjoy having power over children. Anything that diminishes that power, even a tad, cannot be tolerated.
I remember growing a Beatles' haircut when I was in high school. The school couldn't care less, but my father made me get it cut off.
