This may explain why there was a massive disparity in swimming due to the importance of breathing in that sport. There's a lot more to athleticism than muscularity and skeletal structure.
Of course this is preventable by supporting transitions at an early age but people who are most vocal about "the integrity of women's sports" are also very vocal about shitting on transgender rights.
And so you have this trans woman beating everyone in swimming by design so that those assholes can use it as further proof why rights needs to be stripped from trans youth and their parents.
