We have, just that we have standards. We don't want our kids minds manipulated into thinking that you have to be stick thin to get into modelling/Hollywood or "perfect" to do such things
I don't know that I would call Julia Roberts stick thin - I thin she is just healthy. Kinda like Jennfier Anniston. I also don't think that photo was really any different to any other picture of her used for advertising any other product.
I can appreciate what the UK is saying though. As the father of a daughter, as she grows, I'll teach her the same thing. And one of the best examples I can think of is actually from the UK - Kate Winslet. Neither overweight nor skinny, just nicely proportioned and very beautiful.
