Sure its meaningful to others and God Bless their little hearts. And yes I could grit my teeth, or as you suggest, "think of happy anti-religious thoughts". It wouldn't be the end of my world.

But why should the invocation exist in the first place? Of what relevance is it? Would you support a representative of the State Parks or the Lions Club to give a two minute summary of their recent activities? Or maybe a blurb from the Fred Meyer general manager. Or a poetry reading. Or a reading from my diary when I was 14 years old. Or like you said earlier, a reading from the phone book?

Who cares? No importance and no relevance.

But by your standard (if that is what it is), the invocation is "meaningful to many others" and therefore justified. If you and other boro residents might find meaning in the angst of a 14 year old diarist, let me know.
