Silly Title IX claims

The NY Times reports on a busybody who goes around filing complaints against high school athletic programs:

Soon, parents at other schools enlisted his help, and Landau continued to spot unfair treatment.

Girls typically played basketball in the afternoons, and the boys in the evenings. Cheerleaders performed only at boys’ games. Boys played their title games at arenas like the Palestra at the University of Pennsylvania, and girls were relegated to school gyms. His complainted have helped eliminate those inequities.

So the law requires cheerleaders at girls' games? This is ridiculous.
