Criticism of Broad Autism Phenotype

I have some criticism of Broad Autism Phenotype.

Broad Autism Phenotype seems to blur the lines between a neurotypical that has persistent autistic traits and a person with Autism Spectrum Disorder. Tha argument can be made is if s person has a diagnosis or not.

There are also some people that have Unspecified Neurodevelopmental Disorder that have symptoms similar to Autism Spectrum Disorder, but they may not meet full diagnostic criteria for Autism Spectrum Disorder.

It's just so confusing.

My therapist says that everyone is somewhere on the spectrum in some way. A diagnosis only really happens if something is causing problems for a person and with that many people go undiagnosed because they aren't struggling in day to day life.
We still have a lot to learn about disorders and autism is very complex when you factor in the different traits people have and how their personalities and life experiences shape their symptoms.
