The message may be unfolded thus. If you do not wear this shirt, or if you do not approve of the life it celebrates, you are evil. You’re a bully. You want people like Tyler Clementi to die. The superintendent, but not the court, notes that Glowacki was held up to opprobrium in the classroom.
Neither the superintendent nor the court expresses any concern about the massive contradiction that McDowell could order a student to remove a belt buckle because it might create a hostile environment for some other students, while not noticing that the entire school bristles with hostility against Catholics, evangelical Protestants, orthodox Jews, and anybody else who holds that sexual intercourse is to be bound within marriage, between a man and a woman.
Which brings me to my second point. If I hire a man to teach my son economics, I’d be shocked to learn that he’d been using his position to run down my faith. Granted that students, because of their age and the special circumstances, do not possess complete freedom of expression in school, it is equally true that teachers and schools must not capitalize upon their strength, their numbers, and their separation from the home, to advocate what is essentially a religion, with its (peculiar and incoherent) set of universal demands and condemnations.
