Again, you are having an issue with an objective evolution in how security is provided. It has nothing to do with my beliefs. I'm sure there are anachronistic laws on the books about a great many things that simply don't apply today. You shouldn't get to decide to just reinterpret an outdated provision for state militias as some unqualified individual right for near any weapon system. And yet you have and SCOTUS has largely gone along with you. But that's a far greater harm to society in my view.
Well I disagree on the basis of definitional arms. Although we can't entirely discern what it means, "arms" is not some nebulous term. Using that term allows for "objective evolution in how security is provided," because, as you admit, this changes drastically over time...something the founders well knew.
