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.
When I go onto YouTube and search for fandom videos to watch, the main people who show up are non-black. As I keep scrolling, I notice that it’s not just one creator’s who’s videos are showing up, it’s numerous. There are days worth of fandom content on YouTube, but the videos with the most views relating to the subject are the ones made by non-black people.
