I have seen reports on the results of studies which compares the abilities of women and men in flying, and there are some differences. But the conclusion in everything I've seen and read is whatever specific advantages we have as a result of gender, it is a pretty even at the end of the day - and it is always down to the abilities of the individual.
Odd attitudes to women? I've only had one comment levelled at me that I could call sexist, and the guy who made it "had his own issues". So I don't think it counts.
But Mr Bravo (not a pilot) almost always gets approached first when we go to an aviation shop or museum. When he gently points out that they failed to pick the pilot, I haven't had anyone continue to talk to him on the basis that that he must be joking. I think the approach is just an assumption based on statistical probability rather than sexism as such.
