I think some of that has to do with the everreal presence of government in today's day and age. In the wild west, well it was the wild west. Other than the long arm of the law there was very little government or regulation, people did not feel the need that the founding fathers did. In all reality they were pretty free.
Contrast that with today and we have moved more and more issues to the federal level, we have pretty much abandoned the republic for an empire and now we are pushing social issues and regulation to a federal level. This does not end well, it never has.
When we has 50 strong independent governments that had more to do with peoples day to day lives and the federal government just stepped into the states business or rights issues, people had 50 shots at finding a representative government. Not so today, as more and more, the states (governmentally) look like cookie cutters of one another. I think this has set the "all or nothing", "I am not giving one inch" mentality that pervades discussion today, on almost every subject and it is coming from both sides. At a certain point, one side or the other is going to believe they need to stand up to federal government, because they no longer have a representative government and the ones that have guns tend to be of the mentality that those chickens are coming home to roost for their side.
To be honest even classic liberalism is dead, both are progressives when it comes to free trade, and unification of regulations across the globe.
I wish people had a better sense of this earlier social arrangement.
It was the most conservative of approaches to gun possession and was imposed by the town elders who wanted to regulate and order behavior in the public sphere.
Now we find ourselves in bizarro world where firearms politics are exactly flipped: a free wheeling "let-do" policy is championed by "conservatives" and a highly regulated policy is championed by "liberals".
In reality, a historical perspective shows us that the ownership of modern weapons by average citizens is off the charts liberal. That is absolutely where it sits on a political spectrum of rights. It is, historically, the prerogative of the most conservative and reactionary interests to prohibit/restrict arms.
All that to say: I prefer the conservative approach. I, too, was very young once and very excited to exercise my rights and privileges ... I open-carried regularly, had a CCW, etc., and the result was a lot of discomfort and bad feelings. Carrying a firearm is a provocative act and it makes sense that conservative actors in a community would try to keep that at bay.
