I'd have to read the other comments Rogers made and look at Miller again, before I'd conclude on the remark. It's a mistake though to conclude "militia" is a collective that holds right. It's the individuals that hold the right and they make up militia.
A simple rephrase illustrates the point.
A well educated electorate, being necessary for the security of a Free State, the right of the people to keep and bear books shall not be infringed.
The people retain the right, not the collective "electorate". The people simply make up the electorate.
Right. And every judge and legislator with an IQ higher than a turnip knows that as well as we do. Leftist antigun judges and politicians are some of the most brazen liars on this ball of dirt.
