Some people enjoy collecting guns.
Limitations on ownership wouldn't stop you outright owning. There is a compromise possible on the long and challenging road to some sort of reform in America.
I get it, guns are mechanical marvels. People who like anything intricate/mechanically made can appreciate the craftsmanship of guns. Ultimately though, we're not talking about model trains, metalworks, or collecting cars/car parts. Guns have a limited window of use, all of which involves... shooting. Whether it be target practice, vermin, hunting, or yeah, self-defence. Sure you can claim none of your guns are ever loaded and you just collect for looks/mechanical appreciation, but the gun itself is still limited in functionality. Comparisons to cars, knives, lightning or whatever else are just intellectually dishonest and dumb. Even knives if you want to bring them up have some restrictions, especially when it comes to pocket knives/machetes. Although, I actually have no idea what knife laws are like in America. I maybe shouldn't ask.
People that grow up collecting or see it as a hobby are emotionally attached. I get that. Maybe they're part of gun clubs, or go to conventions or simply make lots of friends and social contacts over them. Then the law, or the state, is proposed to come in and say things are changing, you might be impacted. So they get up in arms shouting about how they're one of the responsible gun owners, they have this as a hobby, they've never hurt or endangered anyone. Sure, that's probably true for many people. If you're American though and love your country, you have to take notice of what the flippant and blasé attitude to the second amendment causes across the nation.
Maybe it is going to come down to the bad owners impacting everyone, but there's soo many "bad ones", so to speak. The death counts from gun crime/attacks year on year in America are appalling. As a collective more people, even gun owners that are passionate about guns should be wanting the country to be respected a bit better by everyone in it. Also by eyes globally. Much of Europe looks at America when it comes to guns and doesn't know what to say. It's just outrageous. Civilians thinking they need to carry around assault rifles. It's like a religion that has indoctrinated soo many people past the point of reason.
No matter how much fighting, falling out, screaming, arguing and essays get written from pro-gun and anti-gun sides, there is a compromise for America. Some things need to change now, and then maybe after gun owners see an incremental change has a net positive for the country you can talk other things later down the line. Stats don't lie, right? Well, the stats for gun crime right now are appalling, why not try some changes to see if the numbers can be brought down?
