Female bodies are often portrayed as an inconvenience, with Williams' nipples showing through her tight Nike top drawing more attention than her game play over the course of the tournament. Similarly we're told that young girls are distracting to schoolboys, as if that's our problem rather than theirs. Sport helps us build self confidence that society does so much to destroy.
Perception is everything. First of all, don't jump on me for not using the word 'heroine' in the title. I know some will, but playing the politically correct game of appeasement by referencing Serena's gender is missing the point. An argument pitting men and women against each other in a battle for equality and respect is not what this is about.
