Something which will be interesting will be the first time Elliot Page goes into a public men's restroom. It's not pretty. I can imagine it being quite a harrowing experience for someone who has been using the women's facilities for their entire life.
in this modern progressive age of ours, all she needed to do was say she identifies as a man, and she wants to be considered one. She doesn't need to do anything else, and everything will be fine, just as long as everyone treats her the way she expects to be treated.
In a hundred years or so, assuming we don't kill ourselves, historians will look back on things like that and wonder just what the fuck people in the 21st century were smoking.
