Personally, I have no problem with race swapping if it doesn't affect the storyline or the characters.

For example, the little mermaid. Ariel isn't human. Her skin colour has nothing to do with her character or motivations. Whereas if they switched Tiana's race to white, that would change the impact of the story.

Or the Percy Jackson show that Disney is currently working on. I've seen people get upset that Annabelle is going to be played by a black actress because she's canonically blonde with grey eyes. People have been picking apart a child's future because they can't get over how much melanin she has.
