That's right. Schools have BROAD authority, and hate speech...
   ESPECIALLY the sort that might lead to BULLYING, surely can be limited.

   May schools limit the time, place, and manner of student expression?
   Yes, as long as the time, place, and manner regulations are reasonable
   and nondiscriminatory.
   The U.S. Supreme Court has said that "laws regulating the time, place
   or manner of speech stand on a different footing than laws prohibiting
   speech altogether."[2]^1First Amendment jurisprudence provides that
   time, place, and manner restrictions on speech are constitutional if
   (1) they are content neutral (i.e., they do not treat speech
   differently based on content); (2) they are narrowly tailored to serve
   a governmental interest; and (3) they leave open ample alternative
   means of expression.
   Courts will generally grant even more deference to time, place, and
   manner restrictions in public schools because students do not possess
   the same level of rights as adults in a public forum. However, the
   time, place, and manner regulations must still be reasonable. This
   means that school officials could limit student distribution of
   material to certain locations and at certain times, but those
   regulations would need to be both reasonable and nondiscriminatory.
