You've missed the point that this topic has been beaten to death over and again. Of the nearly 360 pages, you'll probably find 75-100 pages worth of morons kvetching that they don't like Frank's internal monologue, not just once, but some of the same people time and again. Those internal monologues are realistic, but I think the biggest issue isn't that they occur, but something which would last only a second or two in reality, probably takes people a minute or so to process in the game, and they don't like it. Well, tough. As for people going "get over it already", in game time it's only been a few weeks - is that really time for a human being to completely turn around their entire life perspective? Unlikely.
And while you may have the opinion that making changes based on what a few people say would "improve the game", there seem to be more people that don't think those changes would improve the game, and, obviously, CNG doesn't think it will improve the game. Since it's his game and he has plenty of people supporting him as is, why should he change for a few squeaky wheels?
As you also note, it's a fantasy game, yes; but a little taste of reality in the game makes it more enjoyable than "Abby walks in, Frank says he can't resist anymore, rips here clothes off and puts a baby in her, all without dialogue, only with squeals and moans."
If that's what you want, watch 70s porn.
