When my kids were in school many years ago, I told the teacher to stop putting cartoon stamps on my kids, told her it is training my kids to accept the mark. They came home again stamped, I told the teacher nicely again to stop but a bit more firm. 2 days later stamped again.. I exploded on the teacher and school Admin. They never got stamped again. So I would go completely insane if my kids were disciplined for MAGA clothes - especially since kids are allowed to wear Dems support or PP support.
