When considering participation in sport, we rely on fairness as our guiding principle. It is not fair if athletes cannot participate or compete in sport because of their gender identity – participation in sport should be available to everyone. Similarly, it is not fair if an athlete must face unreasonable field of play safety risks or a much-reduced chance for success in competitive sport due to sex-linked physiology – ensuring fairness in sport should be a priority for everyone.
The anti-trans fear mongers aren't interested in fairness. They want absolute abolition of it.
