Yes because as you say, if they like it, then what does it matter whether they are expected to like it or not?
But no because there is still a whole mutual stereotype reinforcement going on. For example, why does Barbie's color have to be pink? Why is everything Barbie owns pink? Wouldn't the girls love Barbie and her stuff just as much if other colours were used as often as pink is? Same with the clothes: why do most girls' clothes have to be pink? Sure girls love pink, but it's not the ONLY color they like, is it?
Or is it? See, that's my problem: by associating all girly stuff with pink, we reinforce girls' natural liking for pink to a point where it basically becomes a straight-jacket, and they can't even think of going for another colour anymore.
How many boys have you known to have a fit because their new shirt is red or green instead of blue? Or to even refuse to wear the shirt because it's not the right color? How many boys do you know who insist on wearing one and only one color? And on having it plastered all over their bedroom too? How many boys do you know who can be sold almost anything and everything just by making it the right color? "Oh, it's blue, it's cool, I want it!" ?I can't imagine anyone getting up in arms because boys like blue.
When I go to my son's kindergarten, there just isn't a color phenomenon for boys, that would be in any way similar to the Pink Explosion for girls. Boys wear all kinds of colors, and it's very rare to see a boy who would be wearing mostly just one color. So really, I don't think it's the same at all.
