Yeah, I made sure to capture the entire sentence so I wouldn't be cherry picking/quote mining to skew it to my "side" of the debate. In 1776, planning a yearly exercise/drill for a town or city was something that would happen when everyone got together for traveling judges, organizing fire brigades, and all kinds of civic tasks.
If you want to start planning a yearly get together for people to have a training day with the national guard or reserves like CERT does for disaster drills, it would probably be a huge hit with the tacticool dads and gravy seals. Would probably get better turnout than the CERT drills that serve critical importance to first responders and make the civilians better at how to respond to disasters too.
You are glossing over that the Federal Government to this day considers every (male) citizen to be the militia. Your saying the equivalent of "Nader's talking about specifically the Pinto, not cars in general when he says our roads are unsafe." I'll even conceed that your right that Title 10 does need to be adjusted to include women, because they already serve in the military and are fully capable to fighting in wars. You are also glossing over Hamilton saying that requiring everyone to be a well-regulated militia was unreasonable, so they would just need to rely on "the great body of the yeomanry, and of the other classes of the citizens" being armed and equipped. That right there is the definition of "every Tom, Dick, and Harry". He wanted to make sure that they didn't neglect to be armed and equipped by checking every year or so. I would like to direct the request for critically reading Federalist 29 instead of just using bits to confirm your bias" right back your way.
If "expecting them to be trained as a military is unreasonable, but we can still rely on them to bring their guns and fight with the professionals with just a little training once a year" doesn't rely on the right of all classes of citizens having a right to be armed, I don't know what else it means. The Militia Acts say the same thing; every able bodied citizen is considered part of the militia, and as such can be conscripted at any time of need. When conscripted, the "every able bodied citizen" needed to show up with a gun, initial ammunition, bayonet, and field equipment.
We have the same system now, except it's called Selective Service instead of reporting to your town hall when you move, except you do that too by establishing residency for local voting and tax purposes.
