I loved Barbie when I was a kid. The sexuality/body image issues never even occurred to me, until I was grown up and people were throwing fits over it.
She is just a doll... She only has as much power as your imagination gives her.
Heck, when it was young, my grandma taught me to sew by helping me make Barbie clothes. I was raised Mormon, and modesty is a huge deal in that religion... Since she doesn't have many clothes that fit the bill, we just made our own. (Far cheaper than buying hem, too!)
Also, I used to cut the hair of some of them short to make boy dolls. (I got a LOT of hand me down Barbies, but had no Kens.) It didn't matter at all that Barbies boyfriend had boobies to me! Lol.
