Personal responsibility and accountability is something that has to exist on both sides of the fence, both the content creators and the consumers of content. While I am not for banning things either, I do have to call-out game developers for stirring up trouble by introducing such games. While one is allowed freedom of speech and personal expression, it is expected that one will be mature and rational to know when and where something is appropriate(for instance, going to church in a bikini is not a good idea, no matter how great you may look in it). It is expected that one is mature and rational enough to realize the effects one's words and actions can have on others and to be appropriately considerate. When people fail to have such maturity and persistently abuse this freedom such to cause unrest, you get these slippery slopes of censorship and banning started.
As for myself, normally in situations with controversial content, any problems I have is usually not with the what but the how and why. Basically, is the content necessary to the story, flow, and portrayed reality of the game, or is it just the developer shamelessly inserting some trite geek fetish? (This game is probably a poor example on that particular point because the whole game is about committing rape; how can you have a rape game and no rape actually occurs?)
Be that as it all may, I will say that I find this particular game in poor taste and definitely not something I would purchase or play under any circumstance, even for the sake of curiosity.
