Autism is just one part of it though.
Every single human being is somewhere on 'the spectrum'. There is no escape from that. All people who claim they are 'normal' are still captured by 'the spectrum'. There is no actually boundaries for what 'the spectrum' is in terms of it's width or scope.
There are two ways to look at it:
aspergers - normal people - autism (the 'traditional' model)
or
normal people - ASD (which includes all forms of aspergers/autism/neuro-divergency) - more normal people
Today, the totality of 'neuro-divergency' as distinguished from people who are defined as 'neuro-typical' is called ASD (Autism Spectrum Disorder).
The big flaw with this is the Disorder part. It is *NOT* a 'disorder' or 'disease' in any way, shape or form. Neuro-divergency is *NOT* 'abnormal' - it's just 'different'
It just means that we neuro-divergents do not see, process and react to things happening around us in the way that the textbook(s) of what the majority of people would consider 'normal' would expect and/or predict.
For example, I'm extremely socially phobic (always have been - I don't do friends), since some bad relationship experiences I'm extremely sexually phobic (though I suspect I always have been since childhood), I do not really understand sexual attachment or the 'fabric' of adult relatioships, and I have a very strong 'bullshit detector' to tell when I'm being lied to about how I should think and feel about something (I'm a committed believer in thinking for myself and applying scientific reason plus critical thinking to how I live my life).
I am demi- and sapio-sexual, which on their own do not count as 'neuro-divergencies', but combined with the other things lead to an assessment of my persona being not neuro-typical as a whole. Yes this is totally self-diagnosed. I have never been 'medically assessed' - I just know.
