I'm gonna break with y'all here... So, as an autistic person, yes, there were things that I was missing, and many understandings of language and innate interpersonal interactions that were just missing from me when I was born that most people just have.
Those DID have to be built, and it took 30 painstakingly long and hard years to get to the point where I am finally surpassing my peers in communication skills
Where this falls down is his badly chosen language asserting the lack of PERSONHOOD. Bad or even missing communications skills do not make someone "not a person". They just make them a "person who is a bad communicator".
But the fact is, I'm more conscientious of my obligations as a person than most people I know and have been for most of my life. Certainly moreso than someone who would accuse me of not being a "person" just because I have a hard time communicating at times.
