The problem is that no other country on this planet has this specific gun violence problem. This is a US specific problem so any factors that are shared with other countries around the world can be dismissed. That leaves pretty much only the gun laws and gun culture in america as a deciding factor.
I've already admitted that guns are the main culprit. What's so hard to understand that violence in media isn't the cause of the problem, but it is an accelerant? People on here seem to keep wanting to place me in this box, where I'm stating that guns aren't the problem, but video games are... that's not what I'm saying. I'm just saying that violence in media primes us towards believing violence is the answer. From there... it's not that far of a jump, skip, and hop away to say, "well, I could solve this problem with a gun." Guns are the problem... but guns supported by years of violent game play is probably a slightly bigger problem. Follow?
Other countries don't have our problem, because they don't have as much access to guns. But we don't know what a society would be like if it had lots of access to guns while still having a censored media. That experiment has never been done before, as far as I know. Probably cause such a thing is contradictory. A society that doesn't fetishize guns and violence would probably not be super interested in having wide access to firearms. So, it's a chicken or the egg situation.. Did violent media give Americans permission to fetishize guns? Or did our fetish for guns give us permission to appreciate violent media. I believe that guns are the source of the problem, and our violent media is the result; however, these two things aren't separate.. they work with each other to create an environment where the owning of a gun is accepted and even encouraged. Would Americans fetishize guns so much, if we weren't crazy about Western movies in the 60s? If we didn't fetishize this whole "I'm an independent man, and I don't need no cops to help me" attitude? I don't know... but I imagine it's all connected. We like guns because of our media. And we like our media because of our guns.
Media isn't the cause.. but it doesn't help. Much more than a tool for defense, I think guns are a symbol these days. A symbol for masculinity, a symbol for personal freedom, etc. The value that we place on a gun is more than just its value as a tool; its value is cultural. And I think that cultural value is propped up by gun related images and literature that we are inundated with as kids.
Now.. I appreciate that this is all just my conjecture. Just my common sense take on it. I understand that there have been studies on this that state that violent video games do not correlate with violent actions, and my personal feelings can't compete with hard data. But as I take a step back, I just don't see how such things can benefit us in any way. Surely there are many American children who grow up inundated with this stuff, and it effects them. How could it not? No one looks at our violent media and is like.... "well, that definitely helps to make us more calm and passive, for sure." It seems obvious that violent media has a negative effect on us... the question is to what degree that is.
