Reckon I'm about to outstay my welcome. Didn't know there were so many nice sensible men out there. Must be hope after all.
Actually, Mercenary Ali is kinda cute. One may very well draft maternal care for offspring when one's own participation is limited to making them (doesn't hurt) and wait till sons are big enough for "manly" activities. Guess daughters have to stay home with mum while the boys go fishing/hunting. Pop provides all the fun things, mum is left to nag about mundane trivialities while cleaning up.
The reason for girls not being attracted to aviation? Starts in early age: Little girls are not invited to participate in technical matters, like learning the secrets of a car engine, going along on a trip to the airport, building models, etc etc. When they get older and visit these areas on their own, the males have already bonded and are reluctant to let them in. Which means that girls who have technical interests must find the knowledge despite lacking a platform. While sometimes being made fun of, and kept out of the "boys club" because they don't master the code. That's life "on the other side".
Cheer up, guys. It's not entirely your fault: Our differences are based on hormones, and we're not talking about changing nature, for heaven's sake. Just take care of the few girls who show an interest in aviation, then more will follow.
