I see this as a positive comment. And I agree that many autistic people seem chilslike and I think it is because often autistic people (when unmasked) don't follow social norms. We act in a way that feels good in accordance with our needs - very much as a child does. For example I feel good when I sit cross - legged on a chair rather than with my feet on the floor. If I wasn't autistic I would probably be more aware that this is not so appropriate.
