I sounds to me like you’re trying to bait a discussion on the ethics of whether people “should” change the race/orientation/gender of characters in stories. It reads more like a statement of fact to me. Humans just tend to model characters in stories on themselves, regardless of the origin of the story. There’s a million examples, here’s one you’re probably familiar with. https://sc.edu/uofsc/posts/2020/07/conversation_white_jesus.php What role does the color of Jesus’s skin play in Christianity? What role does Snow White’s skin color play in the story? Why or when would it be immoral to change those details?
Are you asking this because you feel strongly about it?
