I think it is plain stupid.
Autism is a condition, still very much under study, but already well understood enough to teach people what does in fact imply to be autistic.
Other words that started as medical terms - imbecile, idiot, retard, etc - were readily abused and turned into insults because, as I understand it, there was not the same degree of understanding and popularization of the subjects towards the open society in order to avoid basterdizing the scientific knowledge.
What you describe, plainly put, is dehumanizing.
A Pavlovian response is an automated reaction triggered by a given event, that regardless of context, the individual can not withhold.
The classical example is about dogs being fed after the ringing of a bell. This created the association that food always followed the bell ringing. At some point, only the bell ringing made the dogs salivate, in expectation of the food.
In the real world, how can this influence people?
Imagine you get exposed to something - sight, sound, feeling - and that stimulus is followed by a reaction, be it voluntary, involuntary or even coerced. Give it enough repetitions or a very strong impression and a very hard to overcome association is made, that can stay for a life time.
