This is grossly inaccurate. Sure, it's possible that someone can just be socially stunted in a way that looks "autistic" to non-autistic people. But that's not at all what autism is.

I'm autistic. I have a great understanding of my own emotional state and how it affects my mental function, and I often use this understanding to get myself out of situations before they deteriorate into me having a breakdown. Meanwhile you have allistic people everywhere who will neglect to eat and gradually start getting angry at everything with no awareness of what's going on. Who's the one lacking emotional intelligence?

I'm also perfectly fine at understanding most social norms; I just find a lot of them ridiculous, irritating, and counterproductive, so I'm inclined to fight against them, which goes variously well or poorly depending on the audience. (It tends to go very well around other autistic people!)
