On its website, the Women's Sports Foundation argues that girls should be able to break down gender barriers, while boys really have no barriers to break.
"Because sport participation opportunities for girls have been historically limited, girls have a right to participate on boys' teams if there is no girls' team (or a team which plays by the same rules) in the same sport," according to the organization's position statements. "Since the opportunities for boys have not been historically limited, boys do not have these same rights. While some state courts have found, and there are those that argue, that such a position violates the individual rights of boys, federal courts have found that protecting the participation rights of girls as a previously discriminated against 'class' outweigh the rights of the 'individual' boy."
