Why would I have to prove it?

Given that "fewer women become X because of societal obstacles" has been proven true for many professions over the last couple of centuries, I think the burden of proof is on somebody who wants to claim that programming is some strange special exemption.

I don't think programming is an exception, it's probably similar to many other jobs where we haven't proved that societal obstacles are the reason.
