You know all of those frivulous lawsuits about teaching kids bad things? Most of those are bogus--but this one I'd be fully behind. If someone went after Disney for teaching horrible morals, I'd be behind them.
Ridiculously immoral and violent video games at least put the player in the role of someone with a clearly different background and history. This game/franchise is centered on girls relating to the main character. And what kind of person is the protagonist? A snooty bitch teaching others to be rude to anyone different or unfortunate and form cliques. Of course, the folks that bother with such lawsuits probably like snooty little higher-class girls, and are instead against violence.
