Go check out Volokh Conspiracy. His blog is good as he is a great 1st amendment Constitutional Scholar. He gives this ruling a big thumbs down and says the 9th Circus has set itself up for a 9-0 smack down from the USSC. Not that that is unusual.
As the attorny for the kid put it, what's at trial here is political-correctness, not hate speech or disruption. Sadly, this decision is more rather than less reflective of the popular will of Southern CA. So much for the sanctity of majority rule.
