You're preaching to the choir good sir.
We (the gamers) have debated this with the censors for years. Games do not beget violent behavior. Only those whom are unable to differentiate between the fantasy for the virtual worlds and the reality of the true one are suceptable to becoming violent via gaming.
Now does that mean you should let your 12 year old play GTA? No. (although sadly I knew about 40 kids under the age of 13 who swore by that game series...hooray for responsible parenting!)
The ESRB can place all the holds and censor they want on the gaming industry, but until the parents actually sit down and play the games with the kids, or observe the kids at play they won't truly understand anything other than: "Well the media spin said that gaming is bad..so here son go play outside or something with those nice drug dealers down the block"
There is an almost tangible gap between the gamer and the non-gamer. The gamer feels almost immersed in their virtual world, and interacts with it as it interacts with them. The non gamer sees the gamer immersed in said virtual world, and doesn't understand. All they will see is a kid spaced out; glued to a screen pressing buttons.
Until the gap between gamer/non-gamer (more often than not boiling down to child/parent) is crossed then the misconceptions about games will always be there.
The sad fact is that games are often scapegoated for the bulk of media's negative influence on youth, but the multi-billion dollar movie industry doesn't help matters either.
I'm sure there isn't a 12 year old in the US who has not seen at least one rated R movie. However I'm sure there are many whom have not played a rated M game.
Furthermore they actually ask for ID in most establishments now if you look too young to purchase an M rated title. So this talk of 10-12 year olds playing manhunt 2 or Mortal Kombat and going on killing sprees is groundless spin made by the media to push the blame away from the mainstream industries and throw it at the most susceptible target: youth entertainment.
On an unrelated note: How many other adult gamers are tired of being labeled as childish or immature simply because you stay true to the past time of your youth? I'm 22 years old and have had many an "adult" (someone 40 or over)
whom doesn't understand the concept of gaming, criticize me for the fact that I still play video games. I just find it odd that people who still collect stamps and still build model ships or what have you are left alone by society; yet we gamers can't catch a break.
The fact that the media still blames the video game industry as well as the music industry for all of societies outcasts when their normal tactics of over diagnosing and over medicating them fails, is a sign that the media still has a lot of "growing up" of their own to do.
