Schools should have broad leeway to govern what students wear. Obvious examples of inappropriate clothing include T-shirts with profanity or pornography, and "painted on" pants. Short of the obvious, principals must make judgement calls to facilitate academic, behavioral and social order. A boy wearing khaki cotton slacks and a button-front shirt will feel less inclined pick a fight than when he is wearing jeans and an old T-shirt from a Five Finger Death Punch concert. Principals should set standards and school boards should back them.
Accordingly, a school-sponsored event must have standards, albeit more relaxed. In this case, the principal appears to have abused her power by censoring a political view she opposes, or to have demonstrated starkly poor judgement. A shirt promoting Jew-hater Farrakhan or alcohol use are inappropriate for a school-sponsored event, but a star-spangled, Statue of Liberty torch-bearing, "Trump 45" jersey at a patriotic-themed sporting event was wholly appropriate, as would have a red, white and blue, Obama "Yes we can" shirt.
