Well, without derailing this thread, I disagree strongly with your characterization that it is the law of the land that public religious expression is banned. That is completely untrue.
So long as I am lawfully permitted to be there (I mean, I can't barge into any old classroom without being a trespasser), I can publicly voice any religious thought that I wish. I can stand in the capitol rotunda and do so; I can sign up to speak at City Council meetigns and do so; if I were a student, I could pray out loud in school (again, so long as I wasn't speaking out of turn, etc.). What is illegal, generally speaking, are AGENTS OF THE STATE making such pronouncements while acting in their capacity as agents of the state, or members of the public using mechanisms of the state to make such pronouncements so that it amounts to the state endorsing (as opposed to simply enabling) a particular religious belief.
There is not a single statute or case that bans prayer in schools. Not a single one. When there is free talking time (recess, lunch, etc. -- in other words, the only restrictions are to "time, place, and manner," not content), a kid can pray, proselytize, etc. all he/she wants. If kids are asked to give a presentation in class on "what is most important to me," the kid is absolutely free to stand up and put on a presentation about his/her faith, God, etc. (not that some overzealous administrator or teacher might not freak out over such a thing, or that some civil rights zealot might take offense and try to extend the restriction to such thing -- but those are actions of individuals, and do NOT reflect the current state of the law).
Further, I find the body of law to be reasonably consistent with the overriding theme of the Declaration and Constitution -- leave us the hell alone. Leave me to believe and worship as I please, and do not interfere with it. That also means that the government shouldn't interfere by favoring one faith over another (or even over the lack thereof).
Don't Tread on Me. We should have done more than just put that on a flag. We should have made it the first article of the Constitution.
