The current legislative definition, and the fact that Congress is free to expand it, gives me everything I need. I don’t even need to resort to the myriad contemporaneous statements by the founding fathers describing the militia as the “yeomanry” or the "whole body of the people.

And, lest we forget, this whole argument rests on the complete lie that the right to keep and bear arms is contingent on militia “service”. It is clearly guaranteed to “the people.”
