In this instance, these lawyers and judges "invented" a way to set strict limits on how the government can regulate your speech.
I can't speak for you, but that's a pretty good thing in my book.
That's a double-edged sword: if the gov't cannot prohibit you from making vile, hateful, objectionable speech like the members of the "church" in question do, then it frees them to make this kind of statement and victimize innocents...and further restricts the legal rights of those innocents to any kind of recourse.
I think you need to mention that the "speech" in question was the disruption of a funeral. It was a ridiculous decision.
