That's the only part of your misconstrued drivel that's correct.
You're dead wrong! States have every right to legislate moral issues otherwise there would be no reason for states to have their own judicial systems. IOW we'd all have to go to Federal court when we broke the law for any reason- which would be listed as criminal acts mandated by the federal government. Can you produce such a list? NO! Because The states have jurisdiction.
The states have jurisdiction, but only within the limits of the Bill of Rights. Wich, as we have seen, paints with a very broad brush the scope of our individual rights.
So long as the expression of those rights does not conflict with the rights of others (and no, the "right not to be offended" doesn't count), the states are on shaky ground when they try to legislate one particular morality.
