That is as absurd as blaming the manufacturers of firearms, IMO.
Just as absurd as holding car manufacturers liable for the results of drunk drivers.
On the contrary, neither the gun nor the car contributes to the mental derangement of the user. A video game pumping “kill kill kill” into a disturbed mind, is something else again.
Video games have been around a long time, and although the quality of the graphics has improved significantly over the years, we're still talking about "fake" reality that is easily understood by even children, and I don't buy any argument that a "disturbed mind" may simply be driven by said games into a murderous rage, or even become detached to the point that it makes such urges more likely. At this point in video game technology, the realism is still not there. That brings me back to my previous question:
Let's go back to my belief that Hollywood garbage is much more influential to a “disturbed mind”, as you put it. Why not start at that level? Movies are many more levels above video games as far as realism is concerned. That would be a logical place to start, wouldn't you think?
