Right. That’s why their description of autism is insufficient at best.

Correct but so is the comment above you.

Non autistic people are just as incapable of communicating with me as i am with them, But i can communicate to people that are like me completely fine.

Repetition of a action or series of actions is not a symptom of any disability but a way to manage the actual struggles with living in a society that is not designed to include our way of thinking/living by creating predictable paths that work well for us. Or in the case of stimming to overcome overstimulation senses (by feeling everything much more intensely) by replacing them with comforting known stimuli.
