When I was in school along with the morning announcements over the intercom we had a morning prayer. You could pray along, or not, you could listen, or not. But what you had to do was be respectful of others and sit there and be quiet. That's an important lesson which the morning prayer in school taught, and it's not being taught anymore. Ironically, the prayers were mostly non-denominational general prayers giving thanks for what we have, and asking God to bless the needy and less fortunate, and in asking for His will for others to respect respect their classmates and others, all very liberal things. As a devout agnostic, I didn't then and don't now have any problem with prayer in the schools. Not even a little bit, as long as the prayer or the function isn't to establish one particular religion over another.
