I suspect that there's a tendency from all corners to oversimplify this. For that matter, there's probably a human tendency to oversimplify most things.

Have violent video games in some cases reinforced violent tendencies and caused real-world violence? I expect they probably have.

Have violent video games provided an outlet for people to work off their frustrations and thereby avoided real-world violence that otherwise would have occured? I expect they probably have.

Have some video games by their very nature gotten kids reading that otherwise would have been reluctant? My wife will attest to that.

Okay, I'd go on but that's all the time I have at the moment.
