I totally agree that it's a business tactic to sell more dolls... nothing more. And I couldn't care any more or less about a barbie with tattoos, than one without. People need to get a clue. Like you said, if a barbie with tattoos has more influence on a child than his or her parents, therein lies your problem. And if people are so worried about the effect that a barbie will have on their child, have they looked at the shape/proportions of these freak of nature dolls? Seriously.
On the other hand, with regard to the proportions of these and other dolls... I played with barbie dolls as a kid, and I think I always realized they weren't proportioned like 'real' people, and I don't think I got one iota of what I 'should' look like from barbie... I played with Cabbage Patch dolls too, and I didn't think I should have a fat, overstuffed body, with a huge hard head, either. I mean, give kids some credit here... barbies didn't ruin my self esteem, make me anorexic or bulemic, or distort my perception of what women's bodies should look like. It was a doll, and I don't remember thinking any more about it than that. Now I'm not saying that there aren't some kids who may be more susceptible to those kinds of things, but I think most kids just see toys as toys. But that's just my personal experience.
