"... the whole power over the subject matter of religion is left exclusively to the State governments to be acted upon according to their own sense of justice and the State constitutions."
Ok.....but the Federal Government, by refuseing to take a stand on an issue, leaves the public to believe that it's legal. All it takes is for 1 state to legalize something. Then they move on to the next state and say "well it's legal over there, why can't we have it here?" Then they use the same precedents, examples and referances as was used in the first state to ultamately force it on another. Usually through the Federal Supreme Court that left it up to the States in the first place. This has happened many times before!
If the states had border patrols it would be differant. All 50 states are governed under the same soverignty of these United States. What becomes legal in one state will eventually become legal in all states!
Navydog, did you ever bother to read the 1st Amendment?
