> It also doesn't really line up with the fact that we fawn over genetic quirks that let Michael Phelps dominate his sport. If we think that certain sorts of genetic quirks are unfair in women's sport, why do we allow them in men's?
These are not the same thing. Michael Phelps dominated the sport as a whole, males and females. A genetic quirk to be the best of the world vs a genetic quirk to be a big fish in a small pond (with all respect to females powerlifters, but males just have better records) is not the same at all.
I think a better comparison is one made in the article, to steroids. Steroids are just testosterone after all. Imagine someone put steroids in the food of a powerlifter for 20 years (I'm using this metaphor because I don't want to insinuate that the powerlifter did it on purpose). Do you think it would be fair to let them compete? Stopping them from competing is unfair to them, but allowing them is unfair to all other powerlifters.
