You make good points; I can see you "get" it.
But remember, in High School, at the moment at least, schools provide equal opportunity to women to play sports but dont require their rosters or funding to be exactly the same..But wait, that might happen some day too, just wait and see.
Crew is a huge sport at colleges in the Northeast, especially. Go watch the Head of the Charles Regatta, or sit on the banks of the Schuykill on any warm afternoon.
Most participants have limited rowing experience prior to college, simply because there are not many programs at the HS level. I suspect that this is why it is one of the most often added "parity" sports for women: All they need to do is find reasonably athletic, coordinated girls with good upper-body strength, and they've got a team.
There's nothing wrong with crew, just like there's nothing wrong with fencing, wrestling, track and field, or any of the sports that are getting killed off by Title IX. The problem is government interference in college athletics to promote this silly-*ssed social agenda.
