The posters who have such sympathy for these poor athletes discovering they are no longer eligible for women's competitions clearly don't have much experience of sport beyond school P.E.
Elite sport is a marathon of avoiding injury and struggling year after year to remain top in your field or get cut. For every single athlete in the Olympics there are probably hundreds of almost-rans who were infinitesimally too slow, messed up one critical race / routine, didn't recover from an unfortunate injury in time for selection.
I know athletes who have had chosen not to take medication because it would disqualify them. I've known teenagers who have been kicked off teams because they didn't realise they couldn't take over the counter cold medication and they're classed as doping.
So female athletes, who have managed to clear all these hurdles, put their lives on hold for years, prioritising sport over time with family and friends and progressing at work, and then they get to the Olympics only to discover that it was all for nothing because they are competing against a male who should never have been allowed in their category. Maybe realign your sympathy to them?
