Even if you set up a "womens only" flight school I think you'll find that these things will still occur, if not by members of said club due to it been female only but outside on the apron, unless you want to make a womens only airport?!
I highly doubt a womens only flight school will survive very long as there still aren't that many women pilots about and surely not enough to sustain a fully functioning flying school. Out of the flying clubs i've been to I think there have been around 3 members that were women whom regularly flew... I'm pretty sure they don't get whilsted or ogled at whilst they preflight and are tret with as much respect as the male members.
