“The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.”
“The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.”
I understand the concern, but did we really want to leave those things not enumerated in the Constitution (but included in the Bill of Rights) up to the individual states?
That sounds like a recipe for disaster. I fully agree with the negatives associated with the Bill of Rights that have been exploited by the enemies of the Constitution, but not having those rights such as the 1st and 2nd Amendments left up to individual states sounds worse to me.
I see it as close to the horns of a dilemma. And as most people know, when faced with the horns of a dilemma, you only have three options:
Get gored on the right horn.
Get gored on the left horn.
Try to go between the horns.
It sounds to me like the Bill of Rights is a classical attempt to go between the horns. The outcome is less than desirable, but...you don’t get gored.
Am I seeing this incorrectly? (Note: If I am not seeing it correctly, I won’t take a correction as some kind of attack on me. I am no great Constitutional scholar, though I think I have given enough thought to it that I understand it better than most citizens. I may still not see it correctly.)

Your rights are what ever five-robed tyrant say they are.
