The pending Little Mermaid release has gotten me doing a deep dive into the Disney Renaissance, and I am struck by how queer the whole thing was. Yes, you've got the obvious campy villains, but there are some pretty evident trans themes in both LM and obviously Mulan. In the case of the latter (and from what I know of the folktale about Hua Mulan, I still think this), it's barely subtextual.
"Reflection" is already the saddest of the "I Want" songs: Ariel wants to explore, Belle wants adventure, Mulan...wants to be free to be herself. But put the lyrics, especially the longer version that was only released as a single, in the mouth of a trans person ("Must I pretend that I'm/Someone else for all time?") and it's heartbreaking.
