I was diagnosed as autistic in my early 40s.
When I was younger, the only real portrayal of autism I was aware of was Rainman.
I also know there has been criticism of that because it portrayed an autistic man as a 'low functioning' savant.
Over recent years, I've noticed a prevalence of a different type of autistic person. Usually working in some kind of solitary role requiring a high level of intelligence (eg scientist), who is brilliant/the best at their job but completely lacking in empathy or social skills and getting it all wrong when they have to interact with colleagues or friends.
They're rarely identified as 'autistic' but there are hints along the way, comments from other characters about how 'weird' or 'difficult' or 'awkward' they are or how curious it is watching them trying to interact with or behave like 'the humans/earthlings'. Or other characters have to brace themselves against the tone deaf comments. Basically, either endearingly odd, a bit of a dick or both.
I don't know. It just makes me feel uncomfortable and embarrassed even when I realise this character (and they're recognisable because they're all portrayed in the same way) is supposed to represent me. Or is this really how NT people perceive many of us to be?
YABU - the portrayal of people with autism in films and TV shows is pretty much how I experience autistic people in real life
YANBU - you have a point.
