10 X 0 = 0. If there's no constitutional violation in the expression of a particular belief, then expressing it louder isn't going to create a violation. The court is simply making up the law as it goes, not applying it impartially. It's the typical pattern with activist judges. There's no rhyme or reason to the way they rule; they just find one or two aspects of the case before them that they can latch onto, and then pretend that they've discovered a legal principle. Except it's missing the most important ingredient - PRINCIPLE!
In all their pseudolegalistic attempts at justification, one simple fact stands out: Nobody's rights were being violated. Now they may have imagined that their rights might be violated as a result of this particular expression, but until they can show that they actually are being violated, they don't have a legitimate case.
