It doesn't matter if you agree with the ruling of the SC, it's there in writing.
I'm sure you know all of the above, because you're a smart primate who reads stuff like the rest of us do, but you asked for citations.
https://www.law.cornell.edu/uscode/text/10/246 <---Law definition of an unorganized militia
The 2A doesn't differentiate between 'organized' and 'unorganized', given that those definitions didn't exist when the 2A was drafted. It's possible that if it were, there would be a predication of 'only organized militias', but I seriously doubt it. Conceptually the idea of an 'official' militia and 'unofficial' militia would have been familiar to our founders, and they would have included some verbiage to state as such. Before you try to hang on to 'well regulated', bear in mind that an unofficial, 'unorganized' (again, mind the definition) militia can still be well self-regulated. Again, entirely moot since it was pretty well established from the founders via their personal notes that they never intended to restrict gun ownership to ANY specific body of people.
I'm not citing the rest of my statements as they were simply comments on what you said.
