Christian Barnes-Young writes: "There is a tendency among gamers, and some parents, to dismiss scientific research that indicates a link between exposure to violent media and aggression. Some gamers provide anecdotal evidence to refute the research: "I've been gaming all my life and I'm not aggressive." Others state that researchers are biased against the gaming industry: "Who paid for that study?" Some just consider the entire topic "stupid" and move on. When the subject gets media coverage, the two sides of the argument are typically represented for a few minutes of point-counterpoint and parents are left even more confused. Maybe that's why retail employees have accounts of parents who buy Mature-rated material for their children with the explanation, "It's just a video game."
