Women's teams have lacked support in this area while men dominate. I thought that was garbage and totally unfair when I played sports in high school. We were competitive and played well. In our society men, in most cases, are more interested in sports and shell out more money to support sports than women do. Professional sports exist to make money, not to make sure everything is equal the way schools have to.
Sports leagues are a business and they want the biggest audience possible.
If doing so means creating men's leagues that generate the interest and money the teams and the newspapers that cover these teams want, that's where the focus is going to be. Women and girls have to realize that equality would exist if the monetary incentive was equal. Women choose to spend their money on other things, which is fine, but keep in mind that men are willing to pay to support their teams and women aren't. We can see that from the failure of some professional women's sports leagues. Women's pro teams cater to women's interest, not men's, so don't say that men should support women's professional teams because it'll never happen.
