Minor observation from the photo in that article: Semenya is on the left, they look like they are wearing school uniforms but CS is wearing what boys would wear, the girl in front is in a skirt. Are we being fed a lie that CS was raised as a female? I'm having my doubts.
I've honestly no idea how CS's parents raised them in that sense, however based on interviews with CS it's clear they have never embraced female stereotypes even before their official diagnosis.
Now, that in itself isn't at all an issue.
Women who are gender non conforming are still women.
What is interesting when watching CS in interviews is the level of male socialisation - not how they dress but how they speak (especially about women which is my main concern) and also body language and gestures (things like man spreading and typically masculine gesturing).
It's obvious that CS feels more comfortable with a male social presentation.
Again - gender non conforming women exhibit some of these behaviours but rarely all of them and so overtly.
That combined with the fact that CS has known they are XY since at least 2009 makes claims that CS is fighting to empower women somewhat dubious.
CS is a person who knows they are male yet wants to compete as a woman whilst behaving as a "stereotypical" man and claiming they empower women....
