"text": "The Supreme Court has long recognized that the First Amendment protects student speech. See Tinker v. Des Moines, 393 U.S. 503 (1969). However, this protection is not absolute. Bethel School District v. Fraser, 478 U.S. 675 (1986), established that schools may regulate vulgar speech. More recently, Mahanoy Area School District v. B.L., 594 U.S. 180 (2021), addressed off-campus speech."
