Well, it is hate speech, and it is obscenity. This a-hole deserves whatever comes his way.
Dear Voir Dire,
I know of no actual laws in the United States against "hate speech" (thank God), and as others have pointed out, it's unlikely that this meets Supreme Court definitions of obscenity, no matter how obscene it appears to any of us.
But should a prosecutor decide to prosecute the disruptor, I'm all for it.
I'm just unsure what the basis of criminal prosecution might be, and skeptical that any prosecutor would bother.
