Well, that's not really what he's asking, but that's what I took away from an essay of his on public prayer.
That, and this wonderful nugget:
Any public prayer will at least bind theists together in a shared worldview -- the one that includes the Almighty in some form or other. It is true that the atheists will be excluded, but will they care that much? If they think prayer is just meaningless chatter, why do they make such a fuss? Surely they ought to smile and humor us believers, as one does an idiot child.
