I've read enough feminist "research" about Barbie and I'm profoundly indifferent. I didn't get one until I was eight. Most of her clothes were made out of double-knit polyester scraps by a lady in a nursing home, and she spent most of her time roller-skating, so I missed the whole consumerism angle as well as the feminine beauty skills girls are supposed to learn from dolls.
I also had space Legos. Much more fun.
I don't recall getting any "body image" messages from the doll, possibly because I was getting them daily from my mother and my peers, who spent as much time belittling my "intellectual development" as they did telling me my hair and body were wrong and ugly.
I realize that the experiences of normal women are probably different.
That said, I'm fascinated in this concept that people with children are so stupid they need Democrat lawmakers to make every decision for them. If you don't want your daughter to have a Barbie, don't buy one (hey, that's what mainstream feminists used to say about abortion, back when they wanted it to be "safe and rare"...). If you can't figure that out, you ARE too stupid to raise your own kids.
I want to believe Americans aren't that stupid, but I keep seeing proof to the contrary.
