This pops up in my feed every few weeks and it annoys me every time.
Of COURSE they were focusing on diversity. They were hand picking these stories from thousands of options, being diverse from their usual European princess stories was the entire point. They spent multiple years on every film, did lots of research, took trips, hired consultants. They worked very hard at diversity. Different races, cultures, visuals, sceneries, story types, musical styles, artistic references. Lilo and Stitch was going to be set in the midwest and they moved it to Hawaii for more diverse and interesting visuals.
Pocahontas and Hunchback are explicitly about racism and religious intolerance, and Mulan is explicitly about sexism. Lilo and Stitch had a cut scene about tourists ruining native spaces.
Even Hercules, not pictured here because it was a white guy, had a wildly different art and musical style from all its peers because it was drawing from a very different culture and style of expression (and used a lot of gospel music) and looked very different from everything around it.
It just didn't stick out then as "diverse" because you were a kid and it wasn't yet a talking point to get upset by all the female, colored, or gay characters or anything "woke".
