"Arguments about gender are now so vicious that most high-profile people would rather eat their hair than speak out. But sport, it turns out, is a more clear-cut issue to some than, say, prisons – where various groups have argued over whether trans women should be housed with female inmates. The current ideology is that gender identity is at least as important, if not more so, than biological sex. That is why an LGBT sports group like Athlete Ally can dismiss Navratilova's arguments about male skeletal advantages with a simple "trans women are women". The International Olympic Committee allows trans women to compete if they have been reducing their testosterone for 12 months; but, increasingly, female athletes are saying that testosterone is not the only advantage. Boys start growing bigger bones, muscles and greater heart capacity from puberty, and no gender switch will undo that. One can firmly defend a person's right to live in the gender identity of their choosing yet also look at photos of trans women athletes such as Gabrielle Ludwig, Natalie van Gogh and [[w:Rachel McKinnon|[Rachel] McKinnon]] standing alongside their strikingly smaller female team-mates, and think Navratilova’s arguments are worth investigating instead of dismissing with cries of bigotry."
