As a parent of three teens, I argue this is the parent's responsibility not that of the game designer or content generator. Someone will argue that parent's can't be on constant patrol. Yes, that's true too, thus we find ourselves in a quandary. Personally, I have chosen the side of accepting that sooner or later my kids are going to be exposed to flavors of sex, drugs, and rock and roll that I may find unsavory or not age appropriate - and I'll try my best to provide a framework for dialog and understanding. Other parents will choose a path of extreme restriction or other educational tools (church, etc) for their kids, and they have that right as well. Neither parenting style is right or wrong, but it has to fall to the parents, not to third parties to protect little Billy and Susie's precious ears / morals.
