I couldn't agree more. I have two adult children who are on the Autistic spectrum. My son went to a special school and the school and we worked to make sure that he could fit in to society to the best of his ability. He lives independently and is well-liked. He will never be able to work for money but does a lot of voluntary work. He is well liked but his autism is of the severity that accommodations and allowances have to be made to a certain extent. From babyhood onwards, we have made sure that he accepts rules and takes responsibility for his own actions as far as he is able.
Our daughter has autism of the degree that the OP has. She was diagnosed as a teenager and has a Masters degree and is applying to do a PHD. She works, drives and has friends. Again, we have never let her use her diagnosis as an excuse. She is quite quirky, too.
So many (too many?) people seem desperate to get these diagnoses and then expect everyone else to pander to them. They seem to use it as an excuse to abdicate normal societal expectations. They talk about "hidden disabilities" and "masking" meaning that they are so, so special and everyone else should accept and accommodate their excuses for what is, frankly, bad behaviour. Before I am slammed as unsympathetic, believe me I am not. Indeed, I have a couple of so-called hidden disabilities myself. I have undiagnosed dyspraxia - l don't want to go through diagnosis because it would make no difference to me at this stage of my life but it has helped me to realise why I found learning to drive so difficult, for example, and I don't have a strong left-right sense. My spatial awareness is dreadful, too, which is not helped by my true "hidden disability," the one that is truly hidden and very misunderstood by many people - deafness. I cannot tell which direction sound is coming from and my hearing has deteriorated alarmingly this year to the point where I have had to accept it is a disability and not simply a case of being hard of hearing. Before I had my new, strong hearing aids, l was masking all the time because I could only hear parts of conversations. I had to rely on lipreading as best I could. I have had various forms of deafness almost all my life and just had to get on with it. Most people have far less understanding of deafness than any other disability and also make tĥe least allowance for it. I have to fit ìn to the hearing world which, to be honest, I mostly can with these very expensive and amazing hearing aids. However, even the most sophisticated hearing aids in the world can only boost one's existing hearing and not replace that which is lost. There are still times when I mishear and misunderstand. Do I expect others to constantly pander to me? Of course not. I do think there is a lot in the old saying that what can't be cured must be endured. After all, no one escapes from life unscathed and the person who is expected to put up with all sorts of nonsense because of a family member or friend's diagnosis may be exhausted from caring for an elderly family member or have a devastating diagnosis of their own.
