We women have a pretty good idea of the standards our appearance are compared against.
Take a look at the phenomena of "Good Hair" and all the effort put into it. Chris Rock is even making a movie about it, based on his daughter's distress over her hair.
Straight, long, smooth hair is a natural occurance for only a small portion of the female population... but it is a standard held up to be met.
Hair is just one example, and I only use it for illustrative purposes.
I think Thorn has a very good point.
If Semenya's appearance met different standards, would her performance be so profoundly questioned? (is anyone old enough to remember Zola Budd?)
