Certainly, when you explain how deeming all male citizens in it can be considered organised or well regulated

A group of armed, unorganized men is a mob....they used to carry out lynchings in the last century and before
Yes, all males are required to register for the Draft
You can't be an active member of the regular armed forces and the militia.
Deeming all applicable men part of the militia is the first tier in organizing US citizens for national defense. "Well-regulated" means something with function correctly.
Meaning of the phrase "well-regulated" If you are called to service, it is expected you will function correctly under penalty of law.
So, according to the US government, if you fit the criteria laid out in 10 US Code 246 you are the militia. You may not believe it, but it's true.
The definition of militia, according to Wikipedia is, "A militia (/mɪˈlɪʃə/)[1] is generally an army or some other fighting organization of non-professional soldiers, citizens of a nation, or subjects of a state, who can be called upon for military service during a time of need, as opposed to a professional force of regular, full-time military personnel, or historically, members of a warrior nobility class (e.g., knights or samurai). Generally unable to hold ground against regular forces, it is common for militias to be used for aiding regular troops by skirmishing, holding fortifications, or irregular warfare, instead of being used in offensive campaigns by themselves. Militia are often limited by local civilian laws to serve only in their home region, and to serve only for a limited time; this further reduces their use in long military campaigns."
As members of the unorganized militia of the United States, you can be drafted or selected for whatever military service the federal government desires. You can be selected to serve actively in one of our military branches or you might be required to serve in National Guard units or given a choice. If we were fighting a civil war or invading army, you might be asked to serve in some other capacity such as Army Special Forces A-Teams training scattered bands of Americans to wage a guerilla war.
No, you can't be an active member of the regular armed forces and the militia. If you are in the National Guard you are militia. If you are in the regular army, you leave militia status and are regular army. If you are not selected for service, you are still in the militia. We haven't waged a war on our soil against another nation's regular army since 1812. Unless you also include territories, that would be WWII with Japan's invasion of the Aleutians. The purpose of the militia is that it can be organized to best meet the needs of national defense. Rear Admiral Draper Kaufmann, the godfather of the SEALs, wanted to take American scuba instructors and train them in underwater demolitions and recon because so many Americans who were young and fit were working worldwide. The idea was vetoed, not because the men couldn't be trusted with the work, but any leaks in the program would expose innocent Americans to the danger of being arrested for being spies even if they weren't in the program.
I think you have the official unorganized militia confused with militia groups. Some of them may or may not know they are also part of the official militia.
