Yes, it is sad when white women go missing and turn up dead; I'm not saying it isn’t. But Miraculous Ladybug has conditioned the audience to feel bad for her, and when someone mentions something off, discourse arises because Emilie is what society sees as the perfect woman.
So many of this show’s problems with diversity stem from the fact that it’s only white people in the writers' room; at one point, it was just white men. I was unhappy when I discovered Miraculous was planning to do more specials in different places.
If the Miraculous team refuses to make changes with their franchise, adding writers of color and not having Gabriel go to countries full of non-white people to bully them, they can keep these specials in the drafts.
