The First 10 Amendments to the Constitution as Ratified by the States December 15, 1791
Preamble
Congress OF THE United States begun and held at the City of New York, on Wednesday the Fourth of March, one thousand seven hundred and eighty nine.
THE Conventions of a number of the States having at the time of their adopting the Constitution, expressed a desire, in order to prevent misconstruction or abuse of its powers, that further declaratory and restrictive clauses should be added: And as extending the ground of public confidence in the Government, will best insure the beneficent ends of its institution

The BoR was a Declaration of our Rights. Not a complete list, but protected as part of the "Supreme law of the Land" the "Laws of any State to the Contrary notwithstanding".
It was understood that States could add further protections, but could not detract from this common pool of our Rights. These were to be off limits. From anyone...
That’s very interesting and all, but it just ignores the debates that went on in Congress. Madison proposed amendments that would have bound the states. They were voted down. There was great argument over this. Those that wanted to bind the states lost.
I suggest that you read the debates surrounding the introduction of these amendments in Congress.
