One minute you are saying that the Second Amendment prohibits the federal government from disarming state militias which no longer exist.
Now you suggest that the Second Amendment could be "incorporated" and that then the Nordykes would have a case. The Nordykes are not a state militia. They are people.
If the second amendment were incorporated, that would mean that the USSC had determined that the RKBA was a fundamental principle of liberty and that it should apply to the states. I don't know how the USSC will define the RKBA.
If they define it as an individual right, the Nordykes win. If they define it as a right associated with a militia, we all lose.
