As you all know, I am a gun owner. I would consider myself a firearms enthusiast.
There is no denying that there are many causes for gun violence. So to argue that one single thing is the cause is completely off. People are quick to point fingers toward things they see as wrong; violent video games, ease of access to firearms, motherfucking "assault rifles". They do not, however, discuss the mentally ill. People who would be considered unstable and dangerous.
I think that the number one issue regarding gun ownership is mental stability. You must understand that while you and I do not play games with the intent to live them, there are those in this world that will see something like that, and start to think, "Oh....That doesn't look too hard. I could do that...". They are unstable individuals, sometimes children who know no better, sometimes adults that have snapped. The video games themselves are not intending to be bad. But like everything in life, they leave subtle influences on the people who play them. 99% of us will not think anything of it. But the 1%, the child crying in his bedroom because he feels left out, mocked, and underappreciated; the one who spends his time playing violent games to escape his reality, and become a supersoldier; he may be the one to blur that line, go into his fathers closet, take his gun, and go to school.
Everything plays a part, and while they're wrong to point fingers, you cannot deny that they have influence on people.
If you don't think you've been influenced, let me ask you a question: If you had to pick one gun to use from any video game, which would you choose?
I'm willing to bet you instantly thought of a gun, and I'm also willing to bet it was the "best" for whichever game you chose. Best meaning most powerful and easiest to use.
