I was not going that far.
But to be honest, and I think here we're going to have to agree to disagree, I don't think it matters that much. If a parent decides they're going to dress their little girl in pink and give her dolls then I don't really see a problem with that; when she's old enough she'll make a choice for herself. I was given a dolls house, several barbies and whatnot when I was kid, to see whether I would take to them. I took to climbing trees, making mud pies and generally being a tomboy - I wasn't conditioned by my parents that I had to be a feminine prototype and I do not think that by giving a girl child dolls, or showing them how to cook, conditions them into being a "second-class citizen".
It's great that your parents gave you the choice, but it's not like that for everyone. The point is not to tell gilrls that they cannot play with pink stuff. It is to show them that it is not the only thing available. When you're young society already starts teaching kids what is expected from them. If a girl (not to say boys aren't hurt by gender roles either) walk into Toys'r'us or whatever. A parent, probably without thinking about it, will guide her to the pink section (and yes really pink. I've been there today and there is NO toy that is meant for a girl that isn't pink, literally). She will see dolls, which are supposed to teach her how to handle children (because, y'know, a woman's only fullfillment is in being a mother), little model-kitchens and beauty salons. On the way out she catches a glimpse at the boys' section: the before-mentioned superheroes, playmobil police station, the lego architecture kind of things.
What does she learn? "I'm expected to cook, look beautiful and have children, while men are supposed to save the world, be it with their supernatural powers, or simply a cop, and build houses and be active."
But since this is the adoption thread: a feminine and masculine way is not needed to raise a child. And even if, what are you going to say to single-parents? Their childs "other point of view" is missing, too. Missing normative gender roles actually helpful because it's one person more who will not perpetuate them.
