Why is it that women cannot be as good as men at sports? If women even come close to performing as well as men in any given sport, they must be on drugs or they are really a man.
The idea that men's bodies might not ALWAYS be innately superior to women's bodies at EVERY task deemed important by athletics organizers appears to be a threat to every man.
In both of the situations from the previous links, there is also a huge element of racism involved in the accusations... if a "pretty" North American or Western European woman had a score on par with that of men in her field, there is a better chance that it might be seen as being due to athleticism and hard work, as opposed to "doping" and "tricking" us about their "real" gender.
My new olympic cheer... "Go Patriarchy! Yay!" Now where did I put my pompoms?
