I agree with you too. Which makes me wonder about another thing that you posted about. People have been robbing, stealing, and killing way before video games came about. Hell people have even been going schizophrenic and crap before video games as well.
The one thing that made me curious is how come people didn't go crazy about comic books, fantasy books, lotr, etc. back in the day. Tv shows fit the category too. They're all immersive, some are great, and many are bad. How come someone isn't getting in the media from really good book learned violence, or really good tv show learned violence or something?
If people keep blaming video games for stuff, why not blame some other stuff. Idk if a situation like some dudes going out and killing random people, get arrested, get lawyers, and appear in court. Where the suspects may plead not guilty for reason of dungeons and dragons inspired hack and slash.
