I think the fear is that the language being used by people who experience their interests in a different way will confuse and change the meaning ultimately rendering it useless to communicate the autistic experience. But ADHD falls under the neurodivergent umbrella. (Also many people are misdiagnosed or under diagnosised and so may have autism but not realize it.) So I am hesitant to tell someone that they can't use a term if it fits their experience. I would just try to make sure they fully understood the meaning so they were not using it inaccurately when something like "hobby" might be a better term.

I feel the same way. Thank you for your insight, it was very helpful!

I feel like if the interest fits the criteria, then they should use the word. But I'm also still trying to figure out the difference for my own interests, sorta.

I like catching rollie pollie bugs...I liked catching them as a child and I still love catching them as an adult...I do let them go after a few minutes
