The males who compete in women's sports aren't being marginalized, in fact quite the opposite, they are dominating the competition and causing female athletes to be marginalized in their own sports. It's rank misogyny, centering male demands and desires way above any sense of fairness and safety for women.
If this website is indeed a parody aimed at the male intruders ruining women's sport, then I'm all for it. These cheating men and the sporting bodies that enable them deserve all the criticism they get.
