That is not true that they didn't mean for their "good works" to get political. Gee whiz. They didn't need to sexualize their audience at all. That is political all in itself.
They could have helped the "underserved" population of little girls by delivering free dolls and books to poor communities that showed advances (Girls' Clubs, Girl Scouts, etc.) in helping educate girls. Or even given free things to girls in foster care. Those donations would have been far more meaningful.
