What's interesting about that video is how it is set up to make Archie look like a drooling idiot for supporting gun liberties.
What is forgotten today is that back then, in the sixties and early seventies, the radical new left was very much in favor of the 2nd, and viewed in through the prism that firearms were necessary to protect liberties against a tyrannical government.
I was a new leftist in those days, and the core of the movement was very definitely plotting sedition and revolution, and they intended to use firearms as an integral piece of the strategy. The Black Panthers did not seek to arm themselves with baseball bats.
In fact, many of those currently calling for citizen disarmament and the gutting of the 2nd are the same people who held exactly the opposite view forty or fifty years ago. Of course, now they are the establishment they hated back then.
Ox, meet gore.
