You do realize the reason women are more predisposed to those sorts of roles is because of societal expectations? The reason they'd want those toys, is because that's what's expected of them, not because of some innate instinctual calling... Girls naturally wanting pink stuff? Nope, they like it because from a very early age they're brainwashed by it. Did you know pink used to be considered a boy colour? In fact, all children used to wear dresses, and wore whatever colour

It's a self-perpetuating cycle really, for both boys and girls, they're taught to conform to societal norms, and in turn, they do. This eventually carries on into the next generation, and often gets worse. Which just creates a wider rift between the sexes/genders, which really isn't what you want when aiming for equality.

Also, look how big "friendsip" and "magic" are on the girl's diagram... heh, figured you Escapists would like that. Now note the larger words in the diagrams, it's pretty obvious the sort of values society is trying to instill like this... Do like some people suggested, books, and non-gendered educational toys, or just non-gendered toys. Heck, growing up, I had a sand bucket, and strainer to play with, I was a little archeologist/geologist, and that interest stuck with me from when I was around 5, to today (23) I'm sure many could think of things like that embedded in our minds. Why wouldn't that work for something forced upon us by society?... Self-perpetuating cycle... and we need to break it, let people be themselves, let kids grow up without brainwashing
