Sorry, but IT IS THE GUNS!!! Yours is a false narrative being used by the NRA and others.
This doesn't happen in any other civilized country except this one. The reason why? It's WAY too easy to get a gun in this country, whatever kind of gun you want. This kid is 14 years old. How the hell does a 14 year old get ahold of what is basically a weapon of war?
Why does ANYONE need a gun whose sole purpose is to kill as many people as possible in as little amount of time as possible? You can't hunt with these weapons.
Look, I'm not sure how to answer you. My first instinct is probably be pretty rude and direct, but I'll keep calm.
1. you are correct that it's not common in other countries as often. - HOWEVER, none of them have a constitution that has been interpreted as it being a "right". I'm not arguing whether that's right or wrong. I'm not a constitutional lawyer.
2. You are incorrect about what I'm saying and it being a false narrative. There is something seriously wrong with the fact so many people think it's ok to do harm to others. this is cultural and almost exclusively to those under 30 as of late committing these school shootings.
3. All weapons are technically items of war. The AR platform that is civilian has been around and commercially available since roughly 1963 (precursors designed earlier). But the round/ammunition etc is also available and just as damaging in many forms that don't "Look" like a weapon of war.
4. Yes, you can hunt with these. When you see an "AR" you assume many things. what you don't know is what it's chambered in, etc. etc. Would I hunt with one? Not me personally, because I'm a bird hunter (Quail, Pheasant, Dove mostly) and I use an over under shotgun.
5. most importantly and probably the part you missed in your rush to cast judgement is I am for gun control and quite a bit of it. But I also know weapons and the "false narratives" are what many like you seem to believe. At least go educate yourself on the weapons. that doesn't mean they shouldn't be more controlled , it's two completely different things. keep your views on gun control but at least go learn about the weapons, how they function, what they are and the differences between different ones. I'll tell you why: Because when you say things like "kill as many people as possible in as little time as possible" or "you can't hunt with these weapons" then you lose any credibility with any responsible gun owner or someone familiar. If you want to engage in productive debate and conversation then don't make the other person immediately not take you serious by saying false statements.
