Why should 50:50 be the desired ratio? Are you proposing that every industry which isn't at or near that ratio rife with gender discrimination? Do you also believe there is significant sexual discrimination against men in every industry dominated by women? Have you even considered the possibility that men and women are just interested in different things, simply due to natural proclivities, and not because one gender is actively discouraged? Note that I'm not suggesting that there isn't any discrimination in CS, but simply that there is no reason to believe that 50:50 should be the ideal ratio in this, or any other field, be it currently male or female dominated, unless there's research to support that men and women are both equally interested in that discipline.

50:50 is the ideal ratio if you think that there is no biological reason that men would be better at anything than women (as I do). The key point is interest. Why would women be less interested in CS?

I manage a top tier development team at the worlds largest bank. I go through 100's of resumes.

The percentage of women applying for pure CS related jobs (not business jobs, but specifically tech) is very little.

It's not my problem that a small part of the resumes I get are women. It's not sexism. It's just statistics.

I work a majority of women actually, they out number us very very hard.

I've yet to find a substantial argument for the men against women in tech movement. Did someone yell into your face "get out of my office you fucking WHORE", or is there some VC that subscribes purely to "I ONLY EVER HIRE MEN". Is there some CEO that raped his co workers?

All I'm seeing is a few nancies getting offended at:

a) they didn't get hired likely because they were not good enough, not because they are women

b) women that feel they are entitled to get offended at any little off putting remark/joke/jab.

Downvote me, I really don't care.

Nancies? You know that typically refers to gay men, right?

edit: gay or effeminate, as a slur.
