This article made me sign up just so I can post here.
Much of what I wanted to say is already here; I'm in this 193 comments too late. So, I'll go back to the points on which I disagree with the article. Disagreeing is much more fun anyway.
Point #1: "Rape, on the other hand, can never be justified."
I find this unlikely. Every other crime in gaming is justified by some paper-thin explanation, usually "I'm saving the world." What makes rape sacrosanct? Is it because the victims are so traumatized? The difference between rape and murder is not the magnitude of the after effects, but only on who experiences them. Rape victims hold it themselves, in murder the trauma passes to all loved ones.
A more direct proof would be a rape-justifying plotline. I'll invent one right now. Rape Cell. Your squad has captured a bunch of sexy terrorists that planted bombs in New York, Paris, London, and Tokyo. If you don't "interrogate" them hard and fast, they won't reveal the exact locations of the bombs and how to disarm them. Ladies and gentlemen, I present to you a saved world with zero kills, zero drops of blood spilled.
Point #2: The assumption that there is one kind of rape.
Rape, at it's most brutal, is a subset of the category Non-Consent, or nc as a label for erotic fiction. NC is a wonderful world where "no" means a phalanx of non-no things such as "maybe" or "we shouldn't do this, but you're so darned attractive." Articles like this fill me with fear that there is a movement to take NC away. For a country with free speech, America threatens a writer's ability to explore boundaries an awful lot.
Point #3: Rape games are in the same category as Halo 3.
Rape Lay is behind the 18+ line. It caters to a specific fetish and is therefore for a small number of people. It's reason d'etre is too far removed from Halo's to put them on the same playing field, say, by arguing that killing goes on in Halo so rape can happen in Rape Lay.
The article cites games that contain violent and bloody acts. Rape and Kill are King and Queen of Immoral Hill so if one is tolerated in games, why not the other? That seems to be the logic before we are shown why rape is intolerable and mass murder is. The whole time, no one seems to realize the games have vastly different purposes.
*********Other thoughts********
It is unfair to cross the 18+ line into Adult Land and start saying which practices should be censored. People can't help liking what they like. Thank the gods and the industry that for nearly any desire, there is a rich source of digital media to help fulfill that desire.
As for society, no matter what the fantasy is very few people will get off their butts and do something. Lots of people fantasize about going back to school or starting a business but hardly anyone ever does. Lots of people play Halo but few ever actually kill someone. Those that do usually have non-Halo reasons and kill with non-Halo methods. Those with the prerequisite violence in the brain to actually kill may enjoy Halo as an ideal scenario or creative consultant, but the game doesn't create urges from nothing. Rape games follow a similar pattern. Few dare to dream, but a remarkably small number will actually act. A human who gets off on rape games will seek the rape game. It is preposterous to imagine things the other way around--rape games and kill games seeking out innocent children and prothelitizing.
