Sure women will participate if there were a given opportunity, but not at the participation levels of men. To offer sports just for the sake of having them is stupid. If there is enough interest, and the sport looks like it would maintain, then there is a perfect reason to add a sport. The Billy Packer approach. We don't discriminate in sports.
Sports thrive on popularity and continued interest and participation.
Title IX is taking away from the purity that sport is. When you start adding or cutting sports you are telling people what they can and can't watch or what they can or can't play. If the interest is there then the sport is there and the fan attendance follows in accordance. The Billy Packer approach is a bit extreme, but that what true equality is.
