It was my understanding that those comments in the game were specifically designed to make GLaDOS come across as petty and horrible. Yes, I can see how having the subject come up so suddenly in ones house can be jarring, especially if the parent hasn't had any kind of talks with their child about it (which is most definitely the parent's fault, not the game's), but seriously? THIS is offensive? Okay, so I guess tomorrow, I could call up a news station and tell them about how I was offended by Voldemort's hatred of muggles in Harry Potter, because I'm a muggle and I wasn't prepared to be confronted by that fact by the antagonist in a piece of fiction... Or I could just act like an intelligent human being and realize that antagonists are generally meant to express views opposite of those that the creator of that work holds, but intelligence is for silly people and the murderous, fat, orphan-hating, rapists that obviously make up the gaming community, so we can't have that.
