@hoppet tbh i just say interest. No need to pathologize or other my interests just because it happens to be an autistic person having them. Yes, the interests and how I think about them are different than how allistic people think about them, but the way I as an autistic person think and process everything is different, because I'm autistic.
Though this is just my personal view and others may see it differently and the way they're autism is may make it qualify as its own category, idk
