I just wanted to state that, for the record, having these sorts of discussions on hacker news is extremely distressing to me. I've worked hard to get the accreditations that I have, and I usually enjoy the things I read on this website. But just imagine for a moment how all this appears to an aspiring programmer when she wakes up in the morning and checks her favorite technical content aggregator.
Like, yeah, none of you are saying that ALL women are less capable than ALL men, but what I'm reading here is the subtext. When I pursue a career in this field, how will my coworkers perceive me? Will I be treated with respect? Or will I be seated next to someone who is convinced that there is a gender war going on, and thereby offended by my very presence?
As an immigrant wondering how the natives perceive me, I've learned that one has to do their best and be assertive when it's necessary.
Ultimately it depends on luck. To split the world in ones tribe and "the other" is human nature, and not discussing things on HN won't make things better...
