If groups stopped worrying "how many x are employed by industry y" and simply hired the best person for the job, the world would be a better place. Trying to engineer "equality" into an industry that holds no appeal (yet lacks any barriers for entry/progession/success) for a subset of the population is a waste of resources.
In my years of professional aviation I have noticed that those who bitch the most at women being in their domain are those who bitch about everything being unfair on them (whilst not recognising that their failings are theirs alone, not the responsibility of others).
Incidentally, in my experience in multi-crew, I have found that those who seem to have an innate dislike for female pliots are...female cabin crew.
