This is highly accurate. Presently its a whole set of entirely different diagnosis make up "the spectrum".

They even eliminated "Asperger" and then just folded that into the spectrum as well.

I sometimes think about two women sitting on down on a bench. Once says a bit uneasily "my son, well he is on the spectrum" The other responds with "Oh I know what you are going through my daughter is also on the spectrum"

At this point neither has any idea whatsoever about what the others experience is like.

One may be highly functional, socially awkward and doesn't think like normal people and processes sight and sounds the same. I find myself moderately down this path.

The other may be non verbal and violent.
