As a children's librarian I run into people all the time who think that no one outside a culture can possibly interpret anything about someone or something from that culture. These people get annoyed with me for telling or singing African/South American/African-American/etc. folktales and songs because I'm white.
Then I get the people who think that children should only ever hear stories and songs from their "own" culture. They get mad at me for telling Irish/French/Polish/Norwegian/etc. stories or songs to "children of color."
The kids don't care. If the story's a good one, they want to hear it again and again and again.
I liked the early sixties, when Multiculturalism meant that everybody sang everybody's songs.
