I actually have heard studies claiming the opposite, violent video games decrease violent behavior in real life. There're studies on the sharp drop of youth violence from late 80's to now, correlating to the surging popularity of video games (including violent games) during that period.

It cites studies from the '70s for its most important claim:

"Prolonged exposure to such media portrayals results in increased acceptance of violence as an appropriate means of solving problems and achieving one's goals.14,,15 "

It then spends several paragraphs treating the conclusions of these studies done in a very different era as a modern given.

And later: "Research has associated exposure to media violence with a variety of physical and mental health problems for children and adolescents, including aggressive behavior, desensitization to violence, fear, depression, nightmares, and sleep disturbances. More than 3500 research studies have examined the association between media violence and violent behavior; all but 18 have shown a positive relationship.26"

Look at the title of #26 and honestly tell me you'd trust its claims if you had access to it.

I don't know if I want to keep going with this. It doesn't seem worth the effort with how shoddy it is so far.

because it violates your local social norms? What if I changed it to "Stop Teaching Our Kids to Smoke: A Call to Action Against Cigarettes and Smokeless Tobacco"?

I give people with an agenda less weight even if I agree with them. You're deriving weight from someone deriving weight from someone with an agenda rather than making your own arguments. It's a pyramid scheme of poor citation.
