"if there was no notion that they would be banned, the 2nd Amendment never would have occurred to the founders. It is because they knew governments might ban the people from keeping and bearing firearms that such a civil liberty needed to be protected."
Not even vaguely true. guns were protected at a state level in most places, and there was no attempt by anyone to regulate them really, beyond that. Go look at the state constitutions at the time. Many expressly talk about guns, and they don't match your claim.
"True, but it coups weren't the only things on their minds."
In relation to the 2nd Amendment, it was.
"Yes and no. In a narrow context, maybe so, but states like Pennsylvania (abolitionist no less) had codified the RKBA with the self-defense of the people. Not every new state had an RKBA statement, but states like PA would probably have assumed that the RKBA and self-defense was inherent in the 2nd amendment of the bill of rights. "
You've made my point for me. the FF's left guns - like so much - up to states. Guns for self-defense were NEVER the intent of the 2nd amendment, which is why only their use in militias is mentioned, not self-defense, hunting, etc.
"Maybe not. When standing Armies were created, it made the RKBA even more necessary because coups were even more possible. I understand that modern technology has made it impossible for a civilian militia to win an all out war."
The ONLY way the notion of militias makes sense is in the context of a coup. And frankly it's been a LONG time since civilians could stop the standing army, if ever.
"Not quite. Anti-RKBA people read history one way and pro-RKBA people read it another. The writings of our founders and court decisions are hopelessly diverse and ambiguous on the RKBA. Everyone can find something to support their position because, like today, there were many points of view on the RKBA."
It's not about "reading history". Guns for self-defense was NEVER a thing the USSC agreed on until a few years back. That doesn't leave much room for "opinion".
"Or not."
Don't worry, America will continue to have 30K gun deaths a year, for no reason. Your side of endless carnage has won in the US.
