Read the posted article carefully. Proportional representation is the safe harbor assurance of compliance with Title IX. The only concrete (lawsuit proof) way to prove you are not discriminating is numerical quotas linked to student body make-up. If Farleigh Dickinson coeds are not interested in sports, then the men will suffer. And the Womens Law Center and other lobby groups will sue your pants off if you try to evade the "law". The last thing these groups want to do is quantify student interest (again, read the article).
BTW, Mia Hamm and all these female soccer players benefited from Title IX before there were numerical quotas, not after. So all this bunk about how women will suffer if they stop cutting wrestling programs is really...bunk.
