Japan, has overt, sexual, obsession with barely pubescent girls. While the American WASPs have a covert obsession with little girls.
This we can see from the media they produce. In Japanese Cartoons aka anime, we see a ton of little girls in sexual expressions. (For example, see Wikipedia: Lolicon, Tentacle porn, Japanese pornography) Japan's legal age for copulation is 13 (see Ages of consent in Asia), and the sexual attraction towards young girls is accepted as a norm. Young (teen) girls as sexual objects is in fact a social norm in most of East and South East Asia. In Japan in particular, the sexual obsession with young girls has taken a extreme turn, to the point that their culture in fact developed a infatuation with girls that are barely, if not yet, pubescent, which technically is termed pedophiliac.
While the American WASPs, have a obsession about children, the protection of children, the infatuation with the concept of rape and statutory rape. Meanwhile, if you survey their films, you'll find a unnatural quantity of depiction of little girls, in particular little girls who's blood lines are that of White. In a movie, if the plot line calls for a child, offspring, or young sibling, inevitably it will be a female, and a cute one.
Note: the infatuation of rape, is fundamental in Western culture, with roots in ancient Greek mythology. (e.g. Europa and the Bull, Leda and the Swan, rape of Sabine)
In this page, i start to collect and document this cultural phenomenon.
In the science fiction film Serenity (2005), it features a 16 years old girl named River Tam, who possesses psychic power and physical fighting abilities. In many scenes in the film, the girl is portrayed in a very attractive, sexy way, and also as a victim of torture-like abuse.

In the film Matrix, there's this little cute India girl in the train station. The plot does not require a girl, but it is so. Her name is Tanveer Atwal, a nine-year-old Los Angeles native of Indian origin.
In the film Kill Bill (2003), there's this little black girl named Nikki as a daughter of one of the female assassins. Also, in Kill Bill II, the daughter of another female assassin is a little cute white girl named BB.

In Being John Malkovich (1999), the plot calls for a progeny at the end of the film, and it is shown to be a beautiful little girl named Emily. (Maxine's daughter)
Aliens (Alien 2), features little girl named Newt, as a sole survivor in a alien infested space-colony. Imagine the improbability, and the fervor in Americans's love for little girl.

If you knew a example, where the plot calls for some kid and a girl is used, where the character is shown to be attractive or in sexual ways, please let me know. Thanks.
