One can laugh at jokes about men and women, and there's nothing wrong with being risque, but Duke is thoughtless, backwards, and belligerent. Any hint that constant jokes about penis size aren't the height of comedy? The reviewer must not have a sense of humor.
If a review suggests that it's not funny simply to hear someone use dirty words, that's the reviewer's failing, not an issue with the game. We need to relax, goes the argument, relax enough to laugh at the rampant misogyny and hateful stereotypes on display throughout the game. There's a feeling among some fans of Duke Nukem that anyone who dares to give a bad review to a Duke title simply doesn't understand what the game is trying to do. It's not part of a joke or important to the story the designers of the game apparently feel that you would miss out by not holding some poo in your virtual hand. Why does the game reward you for doing this? I have no idea. In the first few moments of Duke Nukem Forever, your character pees in a urinal and then earns an achievement for reaching into a toilet and extracting a piece of human excrement.
