@chai2,
Sorry chai, but regardless of what society expects or doesn't, girls are different than boys and they tend to like princess frou frou a lot more than boys. This doesn't mean that they all have to or that some boys can't like it too, and, like anything, it can be a source of obsession, just like macho crap, but to think that little girls are being forced into acting like what we all think is "little girl" is ridiculous.
What's wrong with it anyway?
There are a lot of ways to succeed, get your point across, achieve power. Why do they all have to be "masculine" in nature?
Very few, if any, utterly beautiful, totally moronic women have been successful. If you're smart and clever, you use whatever is available to you.
My daughter was a "little princess" and she is now a very successful woman in business, likewise my niece in medicine. My daughter doesn't for a minute regret her childhood, and won't have a problem if her daughter emulates it. My niece, on the other hand, goes on and on about "little princess" syndrome, and vows to do things differently with her daughter. Her father is a uber-liberal, and I'm a conservative. We both have successful daughters, but one seems a lot happier about her life than the other.
