My point of view has been stated several times on this forum. No, I don't think it's fair that athletes who have grown and developed past puberty as men can compete with the women.
However, each sports federation will need to hash it out over time. There is a ton of political maneuvering involved with elite level sports. Much of that never makes it into the public eye.
I appreciate the article, which pointed out in a clear way the biological issues at hand, ended with what matters--the Hannahs of the world. That made me really sad for her and others.
