Do we, however, continue the practice of keeping this a male-dominated profession?
Maybe I'm missing something from your comment,but I can't really see the problem with that.
This job naturally attracts more men than women just like nursing attracts more women than men,and is therefore normal that is a male dominated profession.
A woman who wishes to become a pilot can go to a flight school,get her license and if she's good enough she will get her job,just like any man does.
Basically I don't see any reason why we should forced them to become pilots when the doors are already open (a bit too much nowadays in my opinion)and they clearly tend to chose other career paths.
