Do non Autistics intuitively "know" how to act and communicate?

I read on this website that "Other people appear to know, intuitively, how to communicate and interact with each other, but Autistics do not", but believe this statement to be completely untrue in so many ways.

I do not believe that there is any one way to interact and communicate and nor do i believe anyone, even non autistic could possibly be thought of as someone that "knows" how to act and communicate in every given situation.

I believe making wrong statements like this just causes confusion.

Would do you think?

Do you think there are people out there that just intuitively "know" how to act and communicate? In that case, what happens when they come across someone that has more experience and is more intelligent than them?
