I have to agree with a lot of what you said because growing up in the 50's and 60's no one made gun rights or gun laws a political thing at all.
Sure, everyone knew people who "did not approve of guns", everyone knew folks who hated guns, but were they left or right wing?
THEY WERE BOTH!
And people who OWNED guns were both, too.
I knew five hippie types who owned guns when I was growing up. One guy owned a head shop (and leather goods). Another was a motorcycle mechanic, another was a who guy who worked in his family's liquor store and the others just "had them" for no reason I knew of, they just always had a couple of pistols.
It really wasn't all that political, nothing like today.
Not as extreme as today.
Everyone I knew regarded the anti-gun people the same way one regarded teetotallers, it was just the way they were and it wasn't political, it was, for them, a moral thing. They believed in not killing for any reason thus guns were a NO-NO. That's all.
In fact, in the SIXTIES, one of the very FIRST "gun control measures" was signed into California state law by Governor Ronald Reagan,
the Mulford Act, and everyone knew it was to prevent BLACK PEOPLE from arming themselves. And California was Republican MAJORITY at the time, too.
Oh yeah, by the way, most of the Right Wing conservative churchgoer types were the Right's version of anti-gun by the way.
We can all see how that got changed around.
NO ONE (back then) PUSHED THIS VERSION OF JESUS...EVER.
