The goal of Title IX is laudable and, in fact, Title IX has vastly expanded opportunities for women. The nation has witnessed its dividends, one example of which is the U.S. women's soccer team's victory in the 1999 World Cup. That the school has responded and continues to respond to women's interests and abilities. Or, that it is meeting the needs of women on campus. The effect is to turn the tables so that men have become the victims of discrimination.
Studies show a difference between the sexes in their interest in athletics.
More men than women want to play sports. That's not unusual. More women than men typically participate in extracurricular activities, such as cheerleading, choir and band. Such differences don't, by themselves, indicate discrimination, just differing interests. So, setting a quota based on enrollment is a bad idea.
