"Doing Gender" also discussed how quickly we are to classify people into a gender role. With the example of the salesperson trying to distinguish if he/she was a male or female is one of the first things that people see when they first meet someone. But that since the salesperson's features (voice, hair, clothes, etc) is so ambigious that we're more focused and quick into classifying someone when we see them. "The Five Sexes" discussed how the world isn't just split into two sexes, but instead five different ones. And that could be what Agnes in "Doing Gender" is feeling like. People have been focused into putting people into one of two categories: male or female. When really it is more of a spectrum just like, "The Five Sexes" is saying.
I viewed the TED talk of Ending Gender by Scott Turner Schofield and Scott discusses how quickly people question about transgender. And how if someone came up to ask someone, "what is a woman?" There is no quick answer and that anyone can be a woman if they so wish. And that even the category woman is so diverse in that not all woman are the same. Neither are men. "And you can be whatever you choose," says Scott. And that gender is so flexible that there can be more than just two sexes like "The Five Sexes" discussed.
