You know how, in 1964 Addams Family, they are so so nice and kind, and yet people always hate them, and are scared of them, and find them horrid and weird?
This is point one in my idea of them being autistic.
The episode in which they get new neighbours, they are so nice and welcoming, no matter how odd they find the people. They invite them over for cards, no matter how jumpy they are. They offer their neighbours the things they like, they are certainly nice and friendly. The neighbours are trying to get out of their rental lease, which the Addams happened to be the landlords of. No matter how nice the Addams are, the neighbours can’t stand to be around them. They are not straightforward with their problems, so when the Addams attempt to help, they don’t fix the implied problems. This brings me onto point two
The Addams are not good at reading social cues or situations. This is represented when, for example, there is a guy trying to get the kids to go to school. By the end of the episode, this man ends up convinced that the Addamses are attempting murder against him
They were being nice and welcoming in the way that they are to family members, which as you can probably imagine is an entirely different social script than what most people would consider polite and welcoming
The Addams Family do not mask their “strangeness” because they have a lot of people who support them in their family, and see no need to change for the occasional person who happens to see them as strange.
I love Addams Family so much, I could probably give detailed examples on every character, however I am thinking to hard to think about that
(Disclaimer: this is not to say they wrote them with autism in mind, they obviously didn’t think lets give this entire family autism. The “strange” tendencies they gave to the Addamses, however, do coincide with common autism traits.)
