The U.S. Supreme Court is charged with interpreting the Constitution.<quoted text>
The Constitution doesn't stop public prayer, dude. In fact, it protects it.
It only prevents the government from establishing a national religion.
With regard to the First Amendment, you are incorrect.
The issue is whether there is government "entanglement" with religion.
Whether there is or isn't depends on the specific circumstances of a situation: school prayer, when, how and by whom; religious texts on public buildings; use of public school facilities for religious programs. These are just examples.
The bottom line is that there is no simple answer like the one you have given. It's a series of complex legal issues in an evolving world.
You are entitled to your personal view of how things should be, but you should stay tuned and maintain an open mind, willing to learn and understand.
Is it going to warm up around here, or what?
