US Fencing, quoted in the Navratilova article, state that their trans policy is to widen inclusion and participation in the sport. Which is a noble thought, but surely if someone is keen to fence but is also desperate to transition they could still be easily accommodated as a fencer ( or indeed any other form of sport) under their sex category without losing face or respect - if that was written into the gender constitution of the sport and understood by everyone.
Makes you think that for Redmond the need to fence as a woman but possibly be beaten by other men who were better fencers was not as strong as the need to fence as a woman and be a winner against competitors physically disadvantaged by their sex.
Just throwing that out as a random thought, because of course for any serious sportsperson the sport comes first……
