I’m only surprised that it was the “Bong Hits” they objected to:
The Supreme Court tightened limits on student speech Monday, ruling against a high school student and his 14-foot-long “Bong Hits 4 Jesus” banner. Schools may prohibit student expression that can be interpreted as advocating drug use, Chief Justice John Roberts wrote for the court in a 5-4 ruling.
I couldn’t possibly care less what is or is not permitted in a public school. It’s like worrying about what the cows are being taught at the meat-packing plant.
