If there was ever a field where the current, male dominated, population
wanted women in it, it's CS. I've never met a male CS person that wasn't genuinely happy to have a woman in the room doing CS as well.
I think the issues of men in CS relate more to it being a uniquely problem solving discipline, not prone to the kind of social interactions women want it to be. (I know I'm at risk of stereotyping here, but I think the concept is valid).
I've met some really fine women Computer Scientists, and I never saw or heard from them that they'd ever been materially discriminated against for being female. Anecdotal I'm sure, here's another. My group of college friends all formed out of people in the CS program at my school. We were pretty evenly split along male/female lines. Now, many years later, of our group, none of the women have stayed in pure CS (or some branch like InfoSec), opting to go work in different fields, like requirements management, or managing personnel doing CS type work. When asked why they left? All of them say that the relentless focus on pure problem solving eventually just wore them down and that they craved more human interaction. Sitting in cubes all day hacking out code just wasn't what they wanted to do with their life.
Now, this kind of experience may not be true everywhere, I'm sure there are places where there is rampant sexism. But if a woman wants to do CS, she's more than welcome to do it, and based on my experience, barriers to her presence in the field will not be because of sexism. Similarly, you see lots of thinking about "why so few women in CS?" but you don't see any for construction/garbage handling/music composition/long-haul truck driving/.
I think if you really want to understand the CS question, you have to understand the others. For some of the fields, it's pretty easy to chalk it up to the physical side of the job. But why so few women in music composition? There are absurdly few women in any kind of music composition. I don't mean "song writing" as in lyrics -- there's tons of women crooners. I mean putting notes on a page, or spinning and beat matching discs, or whatever. The demands of the profession are really no different than CS, yet I think representation is very similar.
