No, we are not all “a little bit autistic”! People can’t be “a little bit autistic” in the same way that they can’t be “a little bit pregnant”. You either are or you aren’t! But if you are autistic (or pregnant) there are some typical symptoms and some less common ones, and some rare symptoms too, and some people are more incapacitated by their condition than others.
NT people socialise naturally. They may sometimes think about what to say or how to behave, but that isn’t masking, because it’s still a natural normal behaviour. Compare that to an autistic person who has no idea how to behave in any situation. Everything they do is learned and copied. They don’t understand why these are the rules, they just know that’s what they are supposed to do…
… but crucially, they still fail. For example autistic people know they’re supposed to smile, so they smile, but NT people pick up on the fact that it’s not natural and they find it awkward and uncomfortable, and then they ostracise the autistic person.
My therapist taught me to do what’s called a Duchenne Smile, which NT people respond better to because they find it authentic. All of you who claim “everyone is a bit autistic” have never had to be taught to do a fucking Duchenne Smile, looking in the mirror and consciously contracting one muscle group at a time until you reach a facial expression that is acceptable to society at large. That’s the difference.
The risk is that when you blindly copy the behaviour of a group to persuade them to accept you, you end up copying bad behaviour sometimes. You end up being easily led and doing things that aren’t acceptable… and you have no idea. You end up being abused and taken advantage of. And you have no self, because everything you do is fake. You’re a chameleon. It’s exhausting, like being in a never ending stage play.
