This stinks of jealousy. Why not be happy for the female students? Why rain on someone else’s parade? Something good happening to someone else seems to disgust fringley. Frankly, it comes off as childish.
That's a terrible argument. Can't you say that about any form of discrimination? "So what if all the nice houses and neighborhoods and schools and drinking fountains and restrooms and universities are all restricted to white people? Can't you be happy for them? Why rain on someone else's parade?" There are good arguments to be made for reverse discrimination, but "can't you be happy for someone else?" isn't one of them.
Other issues:
I believe CS and Web Development currently select for certain masculine qualities that are largely unrelated to someone’s prowess as a coder. I believe it is these tangential code-cowboy qualities women are unable or unwilling to emulate, and not their skill or capacity for abstraction, problem solving, creative thinking, or communication — All of which actually make them better developers.
Then she lists a lot of code-cowboy vs. good-developer differences, involving things like "working in teams" and "understanding human elements" and "respecting people" (which are implicitly feminine traits, according to the OP, unlike the focused solitude that "code-cowboys" employ.) This is triply problematic--she dismisses out of hand the idea that men are better than women at abstract reasoning and such, but implicitly argues that the qualities of "good developers" are feminine and the qualities of "code cowboys" are both bad for development and masculine.
After all this, she complains that her talents were viewed as better suited to management, when all that supposedly-feminine stuff like teamwork and respecting people are important parts of management.
Incidentally, I think the reason for the gender gap is something she pointed out in all of this--women are less likely than men to engage in deeply focused solitary activities. Unlike her, I don't see the deep focus and solitude of programming as a bad thing at all--even if it does keep out women.
EDIT HISTORY: Added "There are good arguments to be made for reverse discrimination..." sentence.
