I don’t think the words “rights” and “responsibility” are interchangeable though, that’s what I’m taking issue with.
We have a right to vote, and I think an argument can be made that we also have a responsibility to vote. A responsibility implies to me that it’s a duty of sorts. I don’t think an average American has any sort of duty to our country or Constitution to own a firearm, like I’m not being a good American citizen unless I own a gun or something. That’s how I interpret it anyway, and I take issue with that.
But like you said, the militia clause is very relevant here. Back when states used well regulated militias made up of ordinary citizens for defense, I could see the argument that there’s a responsibility. But that isn’t the case in today’s world.
And I agree, someone with reservations shouldn’t buy a firearm. My dad willed me a gun (or two?) and I suppose I’ll have to do something with them at some point. They’re not in my possession, and that’s by choice. I’d have to buy a gun safe or something for them, clean and maintain them, etc.,and I just don’t have the interest.
