Let me put it another way, when kids watch Snow White, Mulan, Cinderella, Pinocchio, etc they are not aware of what country the stories originated in. What they see is a Cartoon in a fantasy world and the fact that these cartoons happen to visually represent a country or culture is irrelevant to them. The hand drawn or computer animated worlds the artist gave them were designed to look like a particular place in the real world. What I am saying is the same thing can apply to Frozen if you look at it objectively for what it is. The world that Anna and Elsa live in was drawn to look like Norway. The clothes that are worn, the mythical characters depicted in it are also from Norse mythology (Trolls). That is what I meant.
