Is high-level behavior the only criteria for diagnosis?

I think the majority of the public would like to better understand how we came into this position. There's nothing wrong with the topic of autism as research, but it's been a political football for so long that there are many reasonable doubts about methodology, diagnosis, and relevance to everyday healthcare. I understand there may be complications with some patients that require medical diagnosis and intervention, but does that not imply there should be a much more meaningful label on those cases than just the broad umbrella term of "autism"?

On one extreme, we have people thinking they're autistic when they're actually just awkward and inexperienced in life. On the other, we have people with epilepsy who prefer the label "autism" even though they're merely correlated. Something is wrong here. Not with the science, but the discussion.

And you know that they're "just" the latter, and not autistic, because? They don't look like the Rain man?

This requires some citation or justification.

Diagnosis is not a criminal conviction in a North American court of law. In particular, reasonable doubt -- particularly among casual, non-clinical, self-deputized jurists who don't generally have any insight into the patient's chart, let alone medical qualification whatsoever -- is not a sufficient justification to withhold diagnosis.

In your post, you are leaning a bit too heavily on vibes to do the heavy lifting in making your points. For example, you claim there exist people with epilepsy who prefer to be labeled as autistic, but you don't say how many people are doing this, why they are doing this in a way that doesn't strawman, nor why this is even topical.

My interpretation is that you are hoping the reader will have specific visceral (vibes based) reactions to these facts and the drama of the spectacle you've described -- e.g. "yikes, some morons are conflating correlation with causation/identification and using that faulty reasoning to claim a diagnosis they don't deserve". Please correct me if I'm misrepresenting what you are trying to communicate, it is not my intention

My suspicion is that this is a tiny number of people to begin with, and not an indictment of autism diagnosis in the way you believe it is. In fact, most of the people you seem to take issue with are self-diagnosing. What specific "methodology, diagnosis, and relevance to every day healthcare" are you taking issue with then?
