ANY artificial quota system like this is bad. Even more so for sports, due to the economic impact.
In High School for example, the sports are mostly self-sustaining in terms of funds (at least where I grew up). The monies generated from the ticket sales in particular went to pay for a lot of the stuff. However, many of the sports don't generate enough ticket sales/other stuff to fund themselves. The ones that do are Football and Mens Basketball, with some exceptions for schools with really small/crappy teams. And of course there are exceptions in the other direction, such as when a sport is real popular in a region, such as wrestling. But the sports that are not generating money leech off of the ones that do. The Football team with the one or two other money making teams essentially pays for the other teams to exist.
For you see, the money taken in through things such as ticket sales, doesn't go directly to the team. It goes straight to the county to be divided up. And dont say stuff like fundraising. While that can help support a team, it is not enough to sustain it. In addition, things such as concessions only work for some sports (the ones with crowds) so those are not available to help the weak sports either.
In college the situation is improved somewhat, but still most of the teams are money sinks, with Football in particular pulling a lot of the weight, and in some areas, Mens Basketball contributing a lot as well (such as really big teams, like Duke or those found in the Midwest where Basketball i wildly popular).
However, since the schools must fund the sports that few people care about, the big ones suffer.
Title IX is like sports socialism. It hurts the strong to artificially keep the weak alive.
Also, if those feminazis are so concerned about big bad football teams, why dont they create their own female football teams in high school and beyond. Oh wait, lack of participants and spectators. Some things are going to be gender based forever, especially where biological differences make a major difference.
