I haven’t read the article.
The race of a Disney, or Fairy Tale character, should be i indigenous to the culture and place the folklore is from. Arendelle for instance, may have a black princess travel to the kingdom and marry but it is unlikely that she would be FROM Arendelle.
In another example,, Gandalf in Lord of the Rings might be excellent if played by a Chinese man, someone once said. Except the Lord of the Rings depicts Celtic and Norse culture. And there is a reason for that. A lot about the origin of languages, legendary creatures and various myths has its origins in their indigenous settings.
Portraying a mermaid as black in a complete fantasy world is fine. And I’m sure many Danes would insist that a Dane can be any colour. But The Little Mermaid is Danish. Its a Danish tale that involves the history of Denmark or that particular culture maybe interpolated into another kingdom.
There is plenty of room for African stories, such as The Lion King, or beautiful Polynesia,, such a Mulan, in their respective settings.
Lets keep cultures in their place and region so that we can teach more about Hans Christian Andersen and Danish stories.
In a completely fictional, fantasy world, a black mermaid is fine. without a Dane to be found. But it is out of place in Denmark, Sweden, and Norway—cultures long overdue to be portrayed in their era of romanticism.
I have no problem with black princesses, either, in European fairy tales—because royalty might have indeed had connections or ties to African cultures.
So, I’ve stated the counter-argument. Most will disagree. We are teaching about the cultures and settings the stories originated.
