Homosexuality used to be considered a mental illness. The placing of heated glass bulbs on a bare back and the resulting bruises were once considered treatment for all kinds of ills. Medical science has shown both these medical assumptions to be false. Despite that, many still claim that homosexuality is an illness of some sort, and cupping is still performed in many places in the world.
Such interpretations of autism are possible as well.
“Autism is not a disease but social construct.” Such is one position on the causes of autism. Wikipedia explains it thusly:
This is the belief that autism is not really a disorder, but instead is a social construct. That is, supporters of this theory do not believe autism exists at all; they believe (partly supported by recent reference to the rising cases of diagnosed autism) that autism is just the way some people are–that is, a part of the person’s personality, which might explain the apparent difficulty in finding a model and a cure. This is further supported by the fact that autistic people have normal lifespans and their condition often comes with advantages, not just disadvantages.
I can imagine another, even more radical explanation for the tantrums and screaming of autism: “overly-permissive parenting.” When working with autistic children, I see from time to time a glint in their eyes that make such a thought pass through my mind. “They’re faking it, just throwing a tantrum to get their way, and taking it to a higher level than most children.” That’s the easy answer, and I realize that that “glint” I think I see is simply my interpretation plastered over the incident.
The most radical explanation would probably come from the church I grew up in: they’re demon possessed. What person in their right mind would suggest such a thing is beyond me, but I can think of groups whose members would probably easily jump to that conclusion.
But all three explanations (though quote-unquote is probably needed there) deal with our perception of the condition and our notion of what is acceptable in society. Our society considers, in most cases, kicking and screaming as an inadequate adult response to disappointment or coercion. Yet if that _were_ the appropriate reaction, autism would not suddenly disappear. Linguistic difficulties, lagging social skills, an inability to see things from another’s perspective, repetitive behavior, and exaggerated or depressed sensory systems would all remain.
