It seems pretty obvious that it's not just about gun ownership, and about a whole raft of other cultural, economic and political problems. If there is a solution to be had, it must tackle everything, which of course includes what regulations should be on the ownership of firearms and the types of firearms in the first place. But that means little if you don't also address the ingrained belief in the right to bear arms and the ideological position that stems from. Which in turn means a pretty hefty and heartfelt look at the whole Founding Fathers bullshit as well. That in itself is a momentous task that I can't see being broached any time soon. It's so intrinsically tied to narratives around freedom, self-determination, the place Americans* view themselves as holding in the world, as well as the constant politicking back and forth by the Dems and GOP. That's before we get to the power the NRA holds, and how you begin to tackle that in a society that has such a strong libertarian bent and views unregulated capitalism as an expression of their inherent freedom.
It's not at all surprising anyone would jump straight to "regulate guns" because it's the easiest thing to point to. And indeed, it is something that needs to be a part of the solution. But how on earth do you start having the bigger debates? It's unheard of for a President to come out and say what Obama has on mass shootings, and yet can you imagine a President talking about whether Americans should rethink their slavish obedience to 'what the Founding Fathers wanted' or trying to have a discussion about what role capitalism plays in the way Americans are taught to fear to such an extent that they need several weapons at their disposal, or about the power being wielded by the NRA and various religious types and others who have an interest in this kind of society continuing? It wouldn't happen, not least because even the fluffiest Dem has their own interest in the status quo, and an honest discussion of this problem would uncover too much.
