"Momma, Barbies aren't that dangerous"
I think this is something left up to the parents to decide for their particular child or family. I don't feel there is a right or wrong answer to this. You can hardly go into a store or pass a billboard without seeing unrealistic looking women. I think no matter what you do with Barbie you are going to have to have these ongoing conversations with your daughter about body image at some point.
I don't think the article is about the general exposure of young girls to objectified women. Barbie is a toy specifically geared to little girls, which right there, IMO, is weird and creepy. What dad would buy a G.I. Joe for their son that was anatomically correct?
There is also a difference between driving past a billboard or walking past a magazine stand, and purchasing something for our child to play with on a daily basis. Children bond with their toys, and they identify with their toys. Little girls don't 'identify with' a woman on a billboard or on the cover of a magazine, nor do they talk to her and pretend she is their friend. I think that is where the 'danger' lies.
