I thought she was under the impression that she was biologically female since birth and only recently found out she had DSD? If so, I’m inclined to say let her compete as a woman, since that’s what she always believed she was
I get that this is well intentioned and meant kindly, and likewise that it is not nice to see someone sad that the answer has been no - particularly when it is someone perceived as disadvantaged or vulnerable.
But do you see here that you are see female sports and every female involved in them as so unimportant that you'd just hand them over as a consolation prize to an unhappy male?
The comment from the philosopher on yesterday's thread is very relevant here. Female anything is seen as terra nullis - a blank canvas especially to male people, that can be imprinted on or used or colonised for the benefit of male people who need more space, as if it's a space where no indigenous people already are.
Female sport (in fact all female space) is seen as so unimportant, and those females so invisible, that making use of those spaces to raise up unhappy, disadvantaged males seems like a good use of that bit of unwanted space.
Fundamental problem here. Really fundamental.
