On guns: Rural Canadian who moved to the rural South and now lives a stones throw from the article in question.
@nolalady said pretty much everything that needs to be said but I wanted to throw in my two cents.
I was given a handgun by my grandfather when I was around 11 or 12, I was given no bullets and didn't have any access to them. It was impressed upon me that it was not a toy, and that I should learn how to take care of it. I took it apart to clean it and couldn't get it back together again, so I gave it to my uncle. I grew up firing guns, shotguns, pistols, rifles, whatever, pretty much my whole life. I was surrounded by people who had grown up the same way. Whether they were hunters, farmers, military, most of the people around me owned multiple guns and it wasn't uncommon to go out in the back yard and shoot cans or the like.
It's difficult to convince people who have a culture of gun ownership and gun related hobbies that something they enjoy should not be allowed them, especially in a country so indoctrinated with the false aura of "freedom" they hold onto. I'm generally a pro "freedom" kinda guy, I've always resisted the idea that "guns shouldn't be allowed to anyone." I was more in the camp that it should be much more difficult to obtain a gun, much like how I believe it should be much more difficult to obtain a drivers license, but those of sound mind and ability should have the opportunity to attempt it.
It first occurred to me that my perception of guns was not ubiquitous when I was out with some family at a park in a VERY rural part of GA. We heard some shots ring out, pretty far away, across the Chattahoochee, and a couple of my family members who have always lived closer to cities were freaked out. In my mind, it was just some hunter, or whoever shooting their gun out on their property. It's a common occurrence, it didn't phase me, but they were scared. If you hear gun shots in the city, there's very few reasons for it and none of them are positive.
I'm still of the opinion that education, in a more reasonable world, is much more favourable than prohibition. HOWEVER, in light of recent trends and my absolute loss of trust in humanity, I'm leaning more towards more laws and consequences that protect those who can't protect themselves.
Changing the collective minds of those from the camp I grew up with is nigh impossible and their ideals and values sadly control most of our governments. It's very much a "I can handle the responsibility, so you can too" situation. Mix the availability of firearms with a growing disparity in wealth in a city like Atlanta where the youth are trying to find a way out and are only offered "support" through less than legal means and you get this terrible fallout. Which of course escalates when Bubba pulls out his sidearm in "self defense."
And a general worry is that if every law abiding person turned in their weapons, the only people left with weapons would be the criminals, and we'd all be robbed and murdered within the week.
Hopefully this gives you a bit of a window into the American gun predicament. Much like it's not enough that people are dying and we could help prevent it by getting vaccinated to persuade a large amount of people to just get vaccinated, the existence of gun violence is not enough to convince gun owners that they should maybe rethink the whole thing.
