Let me see. . .just thinking of the movies in our box of kids' videos: Snow White, Cinderella, Sleeping Beauty, The Little Mermaid, Beauty and the Beast--all had a female protagonist. Aladdin also had a strong active female character equal to the hero, however unlikely that may be in a Muslim country. The Jurassic Park series had girls and women in strong roles. There was an animated series of about half a dozen videos about baby dinosaurs who could talk, and there was a feisty girl triceratops. Black Stallion was all male, of course. Winn-Dixie had a girl heroine.
I dunno, I think little girls are being encouraged by the media quite enough, thanks.
Oh, yes, and let's not forget the recently-released Narnia, which had three strong female characters, one evil and two good. But feminists wouldn't be happy unless they made Aslan a lioness.
