It's just that a lot of people on the spectrum refer neurotypicals to everyone not on the spectrum, and they seem to forget about people like the girl in my OP. Allistic is a better term to use for all non-autistic people but there's a lot of members here who haven't heard of that word before.
I think AS people seem to think using the term NT is simple, and it is, but when I use it I literally mean "all people without a neurodevelopmental disorder or disability". But then I get asked questions like "but what about people with just depression or anxiety? What about children traumatized from child abuse? What about homosexual people?" all these questions that I'm unable to answer. I don't know! They're in a different category. Neurotypical means no neurodevelopmental disabilities or long-term brain defects/diseases.
Neurotypical doesn't necessarily mean perfectly well-adjusted. It just means standard "typical" brain wiring, meaning no significant (social or intellectual) developmental delays in childhood, or a person with a once "typical" brain develops permanent abnormalities, like brain damage (in a car accident or something) or brain diseases like Alzheimer's.
Emotional disorders in an otherwise "normal" wired person are a different thing to neurodevelopmental disorders. Autism, downs syndrome, ADHD, fragile-X, etc, are all neuroatypical disorders/disabilities that can make affected people different from the norm and can make them face challenges. Even intellectual dysfunction can affect some social skills to some extent even if they're not autistic. For example a person with downs syndrome can be naive and too honest, and can sometimes misunderstand social cues.
I used to volunteer at a social group club thing for teenagers with neurodevelopmental disabilities and they weren't all just autistic. They all went to special schools and didn't have any neurotypical friends to hang out with. That's why their parents or carers signed them up to the group so that they can have a bit of a social life with like-minded people with social and intellectual challenges.
