I addressed that a whole 1 paragraph down.

Sometimes I think that refutation is inherently more attractive than discussion or support. What you think?

Sorry, you made such a sweeping and incorrect generalization that I didn't think a detailed response was warranted. But, since you asked...

"really good at concentrating" by itself is not autism. And as a trait, it is far from universal among people who have ASD. And for those with ASD who can concentrate, that is sometimes to the point of being a disability (hyper-focus to the point of ignoring all else, including personal care). And there's really no such thing as "a little autism" - it's a spectrum defined by having some combination of a larger set of deficits.

If I come across a little snippy, it's because I raised a child on the spectrum. He's now a successful, independent adult, but it wasn't an easy process for him or the rest of the family.

Not really, and the replier's point still stands. ASD has a wide range of phenotypes and not even close to all of them are "good at concentrating"
