Or Dr Sheldon Cooper ?
I think you forget - or did not know in the first place - is that "mild" or "high functioning" autism - what used to be called Asperger's and what can now be seen as an endearing oddness thanks to aforementioned media portrayals - actually can, and does, have days, weeks, months, hell, years - when the reality is that when you come to the end of the day with the same number of family members as you started out with, you call it a good day. Even if it did involve a trip to the A&E and a need for some new internal doors.
And this is the reality that, IME, people used to picture when they heard "autism". Even Rain Man made a big deal of the fact that he had to live in an institution, and that his brother was stupid for thinking he could live with him instead.
This is why I am grateful for Dr Sheldon Cooper. Whilst he has a comedic panic attack instead of a none-too-funny meltdown - being fictional and all - knowing that there are now people around who will accept DD's "quirks" instead of running away in case she decides to start stimming or hurl herself against the wall is not a bad thing - because once you know the person you may stop seeing them as a syndrome.
This is still an uphill struggle though, and we are still only taking baby steps. I really do think that concentrating on the positives wherever they can be found can only help with this. It is very hard for people to accept people with autism as people if they get the impression that even their parents would give anything for them not to have it. Sometimes the only way we can help people change their attitudes is if we change our own first.
It just feels really important to me to educate NT people that yes, there is this thing called autism, and yes, it can be really hard, and yes, people who have it will always be different to the NT majority, but that's actually OK. You do not have to hate it, you do not have to fear it, and they are still people, with as much worth and value as the next person.
