There's nothing wrong with loving Disney films, any more than there is in loving Kaiju movies, anything by Ray Harryhausen, Creature Features, Roadrunner and Bugs Bunny cartoons or Pokémon on the whole.
It's absolutely normal for somebody who is neurodiverse to have special interests. And it's absolutely normal for people of all types to have hobbies, favourite media genres, preferences in Art, culture/popular culture, food, sports and pastimes.
I'm not so sure about wholly neurotypical people who simultaneously deride the special interests of those who are ND whilst making their special interest the basis of their entire identity and personality, though. But then again, people like the tribalism of clothing styles, appearances, music, books, animals/no animals and home decor/cleanliness levels, too. And others define themselves by their faith or nationality or ethnicity. So maybe it's just a modern expression of that human desire to belong somewhere?
