I'm gonna be that Eu guy, and instead of just saying "as usual" or elaborating for hours, I'm gonna make it kinda short :
- Guns don't shoot people, people use guns to shoot people. True, but also, it makes the step psychologically easier to do, and makes gun available at any moment to a crazy person since they are "everywhere". If it were casual to have bazookas, I'm sure there will be more blown up houses in the US.
- Also, the empirical statistics just don't go in favor of "guns are good" in the US. The number of criminal deaths is just insane, per head. I don't think the "per weapon sold" is a good way to look at it. Lot of weapon sold, or not, those kids are dead, that's the thing. If you imagine something silly, just so that I make my point : atomic bomb exploding in 30 years over a big city : "but if you count the fact we have 10 000 nuke heads, it's actually a very low percentage of nuke actually used, so it's fine". To me it doesn't matter how many you can count.
- Tell me how making everyone have a gun is gonna help reducing the number of deaths in the first place, by the way
- The "but at least I can defend my children" argument is invalid, since if every single person has a gun, any single argument can end up in a shooting. Wouldn't it be better if no one got one, and people just argued with their fists instead ? Caricatural yes, but also true. Tell me how this guy would have killed 30 people if he didn't have a gun. Don't say "he could have got one anywhere anyway". Yes but fact is that it doesn't happen so often and so easily, truth is in the examples of other countries. If today I became psychotic and wanted to get a gun, I don't know where I could buy one, unless I had to build up a whole plan for it, and I would certainly go with something else, less efficient. Even with a good sword I would certainly get my ass kicked before I score 30. Those who shoot kids aren't necessary established criminals either, those usually just do their business, drugs, whatever, but those who kill innocents in schools are usually "casual" unstable people. So to me it's better if it just doesn't take an ID and a few bucks to have a simple shotgun.
- Empirical again : almost no guns here, and no bloodbath every 6 months. Last one in france was a year and a half ago and was far from being such a bloodbath, and I don't remember the previous one tbh
- "If a little part of the population has guns, then it's better for me to be on the side of those who have one, just in case". That makes sense of course, but it's just the vicious circle IMO, and doesn't solve the problem in the first place. To me, it's totally not an argument in favor of "it's better to legalize guns". It's only an argument in favor of "for me INDIVIDUALLY right now in this place it's better to have a gun than not, to protect my own family". That's the fact guns are popular that created the problem in the first place.
- The thing as well is the bigger the medias make an event out of every shooting, the more it's gonna inspire new crazy young people. They are crazy enough to find it admirable in their way. Total vicious circle here.
Now I'm being the one in the "target" of pro-gun US guys, I know, but that's ok to debate, and this is my opinion.
