I used to be an educator, and many of my students had an autism diagnosis. I would get to know them and often eventually decide that they were "just like" me, except that whatever their problems were, I had it worse.
So then I would look at these autism checklists and say, "yep, that's me," but when I actually looked at the strict diagnostic criteria, it wasn't that clear.
Looking at this article, I get it. There are other, more focused criteria that can be more appropriate. But those diagnoses don't trigger the special services, so they don't get used often enough.
What is my takeaway? People often don't conform to a model of average human behavior. Being unusual isn't necessarily a grave character flaw (which is what my mother had me believe) but merely an expression of the great variety of human intellect and behavior. It gives me license, without official diagnosis, to enjoy being who I am without shame or embarrassment.
