It's not controversial. It
is wrong (or, at least, misleading), since:
• Allistic people have difficulty recognising the internal states of autistic people; and
• Autistic people have considerably less difficulty recognising the internal states of autistic people (even though there are fewer autistic people from which to learn that skill).
It's placing "blame" on autistic people for what's actually an emergent phenomenon of neurodiverse groups. See doi:10.1177/1362361320919286 "Autistic peer-to-peer information transfer is highly effective", and follow up on any sentences that strike your fancy until you have an opinion.
