Have you forgotten that in almost every book someone has been changed from their original form and part of the story is to change them back? For instance, in *The Gnome King," Ozma and all her household have been changed into ornaments. In Rinkitink in Oz, Bill the goat is a prince. It's called a plot gimmick. Tip the HUMAN boy is disguising Ozma the FAIRY princess, it has nothing to do with her sexual identity or preferences, and the whole LGBTQ movement of today is all and only about who screws whom and how.
