I have zero sympathy for R* or those who demonize them. I don't like the whole violence for violence's sake crap that goes on in video games and movies these days, but I'm not going to say that the movies and games can't be made (should they be made is another question, but I'm not going to stomp on anyone's freedom of speech just because I disagree with what they are saying).
However you won't see me defend the creators when they are slapped with an A.O. or NC-17 rating, or when they are chastised or punished for not removing bits that were supposed to be removed. You made that movie/game, now live with the consequences. Sure it's easier to bypass the unused code than to remove it completely, but if you're going to leave it there you should know that someone will figure out how to access it (Hot Coffee should have already proven this to R*).
As for parents, there is a bit of a gap right now with parents who grew up before the internet and video games were as big as they are now. Unfortunately this also makes them not-as-aware of all of what is going on in games or what can happen on the internet, and they don't really care to find out. It's something their kids do, and their friends have these games so how bad could they be? We're in a gap right now where kids can pull the wool over their parents' eyes because the parents aren't aware of the content in games and the net.
Over the next 5-10 years this will change but they will introduce something new that parents won't be able to control/or have knowledge of and once again it will be the technology's fault rather than the inattentive parents. I'd look to sites like MySpace and Facebook (although they've already had troubles associated wit them), and cell phones for the next bit of damnable technology to become the whipping post while people campaigning against video games will get about as much attention as movie protests do now. Time moves on and the method for delivery of objectionable materials change. There will always be objectionable material out there, kids will seek it and they will usually succeed in finding it on the technology that their parents have the least familiarity with.
