Roger Ebert has a good essay on why the Ninth Circuit was right in the Pledge of Allegiance case.

A snippet:

This is really an argument between two kinds of prayer--vertical and horizontal. I don't have the slightest problem with vertical prayer. It is horizontal prayer that frightens me. Vertical prayer is private, directed upward toward heaven. It need not be spoken aloud, because God is a spirit and has no ears. Horizontal prayer must always be audible, because its purpose is not to be heard by God, but to be heard by fellow men standing within earshot.
