Of course, developing minds are much easier to influence in any way, but if a parent is concerned about the way their kid is developing, they need to get involved, and not just simply blame "damn video games". I'd argue that video games can even help people who aren't great at socializing in person, because if they feel uncomfortable, escape is just a few button presses away. In the end, I just think parents need to assess games on a case by case basis, and help their kid develop to be decent. Seen too many parents let their kids go rampant and get into serious trouble because they never said no! And yeah, most designers I work with are pretty crazy!
