The court rulings do.Courts exist to regulate disputes. Court decisions are not static but move with the interpretation over time. You're statement is still incorrect - The Constitution does not say anything like what you attributed to it.
This idea has been soundly rejected by the courts.Public schools are run by an administrator hired by a school board, to follow federal guidelines and to meet state and federal standards of learning. Again, it's more accurate to say public schools are FUNDED by the government, and then in turn by the taxpayer.
Good luck in court.Wrong again - (purposely perhaps?) Teaching children religion in public schools does NOT violate the establishment clause, it violates Case Law.
You don't get to use both. Pick either case law or your own version.You're ignorance on both case law and the Constitution are seemingly limitless. Please, post more so I can correct you.
