You would see the world differently if you were autistic. It is Nagel's "what is it like to be a bat" isn't it? Having an autistic child, gives insight into it, but not the experience of having it. I suspect there are only a handful of people in the world who know what it is like to have some of the issues I have, but I suspect that most people can never know. Yet, I can provide some insight, and this might help them deal in some other area, whether adjacent or altogether different. We only ever get to truly experience the life we are born into, everything else is through observation, secondhand experience, and assumption.
You have said recently "don't assume" and that you don't judge others, right? How do you know I would see the world differently if I had an autistic child? Because you do? Isn't this an assumption and a judgement? It might be accurate, but it isn't absolute. I might not be different at all. We all make assumptions and we all make judgements of others, on how they should act.
