Perhaps the author was thinking about a strong form of Autism that pretty unequivocally makes life difficult?
I was diagnosed with Asperger's later in life. I received this diagnosis after I already had a successful career, happy marriage, and house full of kids. Not much of a hindrance, right?
On the other hand, my brother suffers a much more severe form of autism. He does hold a profession job in finance. But he otherwise requires a full-time caretaker, tons of medication and understanding, etc. No friends. He's not self-sufficient.
It's a huge spectrum.
In many ways my life has been just fine: steady well-paying employment, wonderful wife and kids, etc. So as with you, being (probably) somewhere on the spectrum isn't correlated with a crappy life.
But...
I've also had some unusual personality traits for my whole life, and I've really beaten myself up regarding them. Once I had a probably Asperger diagnosis, I felt like a tremendous weight was lifted. I no longer felt like I was uniquely messed up in those way. And maybe the subconscious logic is that if I'm part of a cluster of people with these idiosynchronies, maybe there's an underlying physiological cause that's somewhat out of my control, and therefore I'm less morally culpable for my atypical social failures.
As part of my BPD the psychiatrist gave me an ADHD test, 25% of people with BPD also have ADHD.
But I don't care to use the word disabled in describing myself. Being unable to keep my mouth shut in the face of something I don't agree with doesn't qualify as a disability. My sensory issues aren't anything I ask for accommodations for. That I prefer to spend more time away from people than the average bear is not a disability. And in the context of autism, it's hard to use the word disabled and not have people place limitations on what one can/can't do. So, I don't use the word. And just consider myself different.
I recognize that there are people deeply offended by people like me, who are at the higher-functioning end of the spectrum and refuse to consider themselves disabled. (They see us as impostors.) There are also many people who take offense to the term lower/lesser functioning, and resent the use of terms like "severe autism". They consider this language to be demeaning. Autistic twitter is quite the landmine for semantic wars of this sort.
You can function obviously, but not as society expects you to or even in way they can understand. For that reason, you receive the label of "has a disability".
The term "disability" is unfortunately as much a reflection of societal norms as it is genuine medical diagnosis.
As I understand it, the problem with using the expressions "lower / higher functioning" is that it evokes the idea that problems of people with "lower functioning" are a strict superset of problems of people with "higher functioning".
In reality, it's more like there is a set of symptoms, and some people have a larger random selection, and some people have a smaller random selection, so it is possible to be "higher functioning" but fail at X, or be "lower functioning" and fail at everything but X. So the "higher/lower" is more about how much your specific set of symptoms disrupts your life, but it doesn't imply which symptoms are present or absent.
But people who see the "lower / higher functioning" as two sets of symptoms will judge you by presence or absence of one specific symptom.
(Also, with some symptoms, how much they disrupt your life depends on what environment you live in.)
> Autistic twitter is quite the landmine for semantic wars of this sort.
Twitter seems to evoke the worst in people in general. The explanation I wrote here would almost certainly be also considered highly offensive by someone.
As an aside, I'm really disappointed it's all under the umbrella term of ASD now. People are generally more aware of the differences now but no thanks to that.
0. I like ASD better because aspergers sounds like ass-burgers TBH and once explained it makes people understand immediately that you have various degrees of it.
I'm probably guilty of not viewing this as disabling because I'm treating the term too concretely, as if a disability has to be something "physical" that might require special accommodations. But yeah, I suppose my challenges in understanding the game of love are disabling.
Lactose intolerance in adults is something that the majority of our species lives with. It's only the Indo-European minority that can keep drinking cow's milk after puberty.
So, for example: Eye contact aversion. Prevalent among autistics. But only a disability in cultures that equate it with dishonesty.
Inability to tolerate fluorescent lighting. Those damned things did not exist until what, 60 years ago? How is it a pathology to be averse to them.https://en.wikipedia.org/wiki/Yao_Ming

As well, some of the "tall genes" are associated with connective tissue and other health problems:

I'm average height for the West, but when I'm in Asia, I often hit my head on gates, taxi doorways, etc. I imagine that would also happen for 7 footers in the West.
Being on the spectrum without learning how to work around neurotypicals is the issue, the same way that being 7 foot tall without the physical modifications needed to support that body is also an issue.
I am very much on the spectrum but have developed a large number of coping strategies [0]. Had I been diagnosed and treated as a child I would have never had the ability to become anywhere near as successful and fulfilled as I am today. Instead I would have been drugged into being an office drone and probably been looking at suicide about now.
[0] One of the odder ones that no one neurotypical understands is an algebra of social relations I use to model office politics. It lets me evaluate the social graph analytically several jumps further than any person can keep in their head.
