What does that say? What does it say? it doesn't say except on government property, it says "OR PROHIBITING THE FREE EXERCISE THEROF" of what? RELIGION, what are they doing? PROHIBITING.
So no, freedom OF religion isn't freedom FROM it is freedom for them to practice it and freedom for you not to, it doesn't mean that you have to pray but it does mean that you or anyone else cannot prohibit others from praying ANYWHERE.
Would y'all be ok with this city council starting out each meeting prayer with "Hail Mary, Full of Grace, The Lord is with Thee.... "? I mean, since it isn't an endorsement of anything and all, it should be ok, I should think.
You can never be safe from a government that can keep you completely safe from each other and the world. You must choose.
