I think my HN client was bugging out because all your comments were displaying as ** Ignore me

Automatic weapons were in fact in the public consciousness at the time of the founding, and the Gatling Gun existed and was used in the Civil War with no restrictions on who may own one.

I dare say, this thought that people so well read they could architect a country were not aware of the State of the Art in weaponry is rather naive.

If it is naive to disbelieve the founders foresaw a future in which automatic weapons and bullets would be so lightweight, cheap and accessible to civilians that anyone could buy them and go on a rampage by themselves that the State could not suppress without dozens of police and SWAT teams you can call me naive.

Gatling Guns came well after the Founding, were large, heavy, hand cranked, cost between $1000 to $1500 to purchase and required a four man crew to operate. They cannot compare to modern weapons.

The Founders were intelligent and capable men but they were not infallible. They knew that too, that’s why Amendments exist.

I don't think any of that is relevant. It's obvious they didn't mean that they only wanted citizens to have the right to bear inferior arms and that only the government should get the more advanced or powerful weapons. The entire point is being able to oppose a tyrannical government.

I can see an argument over nukes, but this "they didn't imagine assault weapons" is just some kind of gaslighting. They imagined sufficient arms to defend oneself against authority.
