The Federal Government has been given so many powers that the Founders intended the Federal Government to never have, I think we get even the Bill of Rights all muddled.
Take the First Amendment:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
This does not say the states shall make no law. In fact at the time the Bill of Rights was ratified, there were a number of little theocracies that existed among the various colonies and they were not at all tolerant of any religion but their own that all citizens were expected to respect and obey. Congress was not allowed to interfere with that in any way. Such religious convictions extended to the press and the right of assembly and petition to the local government.
The First Amendment was to restrict the FEDERAL government only. The Founders in their wisdom expected a free people to make mistakes, to get it wrong, to screw up, to mess things up, but eventually, through trial and error, through experiment and process, they would arrive at a moral and just society. So without any interference of any kind from the feds, all those little theocracies dissolved themselves and ceased to exist. And no new theocracies developed.
Ditto the Second Amendment. It does not suppose that there cannot be weapon free zones in schools, court houses, bars, or even cities, counties, or whole states if that is what the people wish to vote. The Second Amendment prohibits the FEDERAL government from restricting the people's right to bear arms. Again the Founders expected the people to need some trial and error to get it right, but ultimately most places settled on reasonable regulation and restrictions on the use of firearms and an orderly society was achieved. The feds needed to do nothing at all to achieve that.
And so forth. . . .
The Tenth Amendment was intended to cover everything that was not specified in the existing Constitution and Bill of Rights so that the people in the various colonies/states would retain the power and the Federal Government would be restricted from seizing power it was never intended to have.
The Founders intended that we the people, a free people with unalienable rights secured, would use that liberty to form the sorts of societies they wished to have.
That concept is derailed every time somebody thinks it should be the Federal Government that orders what society should be. And each time it does whether it be what sorts of firearms we are allowed to own or what constitutes a 'hate crime' or whether insurance companies have to include contraceptives in their coverage, we lose a little more of our liberty, and become something less than the great nation the Founders intend that we be.
