How is an autistic Barbie doll interpreted?
I'm not sure how this will work.
Let's face it, Barbie is all about looks, but autism isn't usually detected just by looking at someone. It's in the behaviour, not in the appearance. So dressing Autistic Barbie in head phones for example is silly, because anyone, autistic or not, can wear headphones. I guess the rolling eyes could be seen as not making eye contact but the rest is pretty insignificant to the condition.
Anyway, I can't see the problem in the OP. There's plenty of Barbies for all, and children can use their imagination to make the dolls to be whatever they want.
