When I was young, I had a set of dolls from a bunch of different nations with their different traditional clothing / attributes. I don't understand why this is offensive. I loved the idea that there were so many different types of people and cultures in the world. Isn't that why people travel? To see they way people live in different places? It's why people go to a luau in Hawaii or to see the temples in Asia, or the Mayan ruins in Mexico.
