OK, I misunderstood your gist. The 14th amendment gave more rights to the people by applying the Bill of Rights to state as well as federal governments. That is a goos thing, IMO. There is a lot more involved than state religions.
But the 14th did NOT give the federal government additional authority over the states. The only thing that has done that is a vastly misrepresented SCOTUS decision that states the federal government has the right to pass laws that pertain to those powers granted under the Constitution. That is where the "promote the general welfare" clause of the taxation powers comes into play.
What I find sad is the SCOTUS decision that stated the federal government has authority to pass laws necessary to exercise the powers granted in the Constitution contained the caution that such authority should not be granted liberal applications. Yet far reaching, WAY out of the scope of the intent of the decision applications is the rule today, rather than the exception.
Of course, all is not QUITE lost (yet). To implement their plans the feds are often forced to resort to economic blackmail to leverage states to comply. With that in mind, if the states, in a "popular uprising" format, would start telling the feds where to get off we'd find ourselves better off.
As an example that it can be done, my home state has absolutely refused to cooperate with the federal ID mandates. Not only is Montana not implementing federal ID policies, but we have actually passed a law that forbids compliance, and requires all agencies to report any attempt from federal agencies to locally force compliance. That's pretty much a big FUCK YOU to the feds on that issue.
I LOVE living in Montana!!!
