The 2A is interpreted both popularly and legally as an individual right: it is the right of the people, not the right of the militia.
And, as I’m sure you know, the term “regulated” as written in 2A does not mean the same thing as “regulated” in terms of “government regulation”. In context, it means approximately “well-functioning” or “reliable”.
In historical context, the “militia” was everyone, every able bodied person who could participate in common defense. It wasn’t a specific organization like we’d think of today
Beyond that, the right is entirely unconnected with service in a militia. That clause at the beginning “A well-regulated Militia …” does not scope or bound what comes next; it offers one explanation for why that right is protected.
SCOTUS explained the historical meaning of these words in more detail in District of Columbia vs. Heller, including an in-depth examination of the language as part of its opinion that the right is an individual right.
> 1. The Second Amendment protects an individual right to possess a
firearm unconnected with service in a militia, and to use that arm for traditionally lawful purposes, such as self-defense within the home.
> (a) The Amendment’s prefatory clause announces a purpose, but
does not limit or expand the scope of the second part, the operative
clause. The operative clause’s text and history demonstrate that it connotes an individual right to keep and bear arms.
In current federal legal context, the "militia" is all men between like age 18-45, plus all people in the national guard, or something like that. That's what the US CFR says.
Are we really to believe that slave states ratified the 2nd amendment with the belief that they were giving every individual the right to keep and bear arms?
Because that seems absurd given their rather large population of slaves.
The militia is every able-bodied person, both as a matter of history and as literally defined in US law for centuries. Furthermore, this militia is expressly recognized as "unorganized" in law i.e. separate from organized militias created by the government.
In the US, the militia is explicitly independent of the government. Even if one were to accept your narrow reading, which no court has, I don't see how it would materially change anything given that any random group of blokes without any government involvement is a militia as a matter of law.
give up guys.
