I don't recall the particulars of your argument (and haven't attempted to refresh my memory

). I seem to recall taking an idealistic line the Bill of Rights ought to apply to the states but not in the pattern that has been adopted.
So, for example in regards to the 1st amd, where it reads, "Congress shall make no law respecting religion..." I argued that a plain reading of this indicates that it refers to the Federal congress, and that if we wanted to incorporate this so as to apply to the States, then there should at least be an attempt to do so as an analog: the state equivalent to 'Congress' should be what is affected. Hence, state legislators would be prohibited from making laws respecting religion.
But this was the idealistic route which I believed had the advantage of being reasonable and coherent. :) It was never my intent to communicate that I expected our legislators, judges, and the like to be reasonable and coherent. So, the first amd was incorporated to apply for to the states and instead of having some clear notion of precisely what that would look like, instead we have a mishmash of feelings about how it does apply. It has come to be interpreted so that no person can, while in the capacity of a 'public' position, do anything that may conceivably (no matter how implausibly) be construed as 'respecting religion' (where 'religion' exclusively means Christianity). This is, without question, outside of what the founders intended and leads to a lot of nonsense besides.
Better would have been to revisit the matter and pass another amendment which is clear and reasonable and determined through public discourse with eventual legislative ratification. But that is the idealism talking.
I believe the current method of doing business is a mere shell of what it means to respect the 'rule of law.'
However, the second amendment is of a different nature. The first amendment clearly and explicitly singles out the Federal legislative branch, and so a plain reading of it would keep it there. The second amendment does not have such language at all, and to me a plain reading of it would suggest that this amendment at least would be immutable across the country, wherever the constitution is in force.
So, you said in a post above, "The right to bear arms is a cherished principle among conservatives but so is states' rights. The two appear to be on a collision course."
But I don't agree at all, because while the 2nd amd has generally been construed (as in this latest opinion) as allowing that states can still regulate guns, the language doesn't really support that. The 10th amd rams home the fact that powers not specifically given to the Federal government are reserved to the states- but even the states cannot take away those powers specifically given to the People by the constitution, which is clearly the case given in the 2nd amd:
A well regulated militia being necessary to the security of a free State, the right of the People to keep and bear arms shall not be infringed.
In short, a plain reading of the second amendment makes it plain that under the Constitution that here is a right ascribed to the people that no government has the right to infringe, whether it be Federal, state, or local.
The first amd:
"
Congress shall make no law respecting an establishment of religion,"
3rd amd:
"No
Soldier shall, in time of peace be quartered in any house"
Etc, etc, until the 10th:
"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."
These little words are all important, and I believe they were chosen extremely carefully by the framers, and that the current method has been to dispense with the words in some vain attempt to think we can get at the principle in play without them. And I think that is very bad policy.
But I did not, I thought, argue that this isn't the policy that would be extended. If I did, I misspoke, or perhaps I hadn't formulated my thoughts yet sufficiently.
I suppose that I should just be happy that some measure of the rights given to me- as a member of 'The people' by the Constitution has now been graciously bestowed upon me, all Praise to the Men in Black Cloaks. But what they giveth, another court can taketh, since notions that we should be constricted to the actual words on the page have been dispensed with.
(And, if we felt that the 1st amd's controlling principle was valid, but unfortunately didn't explicitly apply to the states, my idealistic solution is to make another amendment which does, and not bastardize the one we've got until its virtually unrecognizable.)
