If this is a trend, I very much doubt it's unique to women, and it is more likely correlated with social difficulties and such that those of us on the spectrum (i.e, not looking approachable, communicating in a more unique and perhaps a more awkward dynamic than most NT's are used to, etc).
Even if true, I don't think this is by any means a condemning statement for us ND folk, though it may be an extra hurtle to jump over for some of us. I have encountered people on the spectrum who are quite exceptional. Only the other day, I met an aspie guy who is a model/dancer.
Also, chances are you haven't met many aspie women, so you probably aren't basing your statement off of very much. I've met tons of aspie guys in real life, but much fewer aspie girls. As I'm aware, the diagnostic ratio between men and women on the spectrum is 4:1, so aspie women (or at least officially diagnosed aspie women) are far less common than aspie guys.
