I went to a high school where the two calculus teachers were both female. I also went to a math PhD program where a professor -- specifically George Mackey http://en.wikipedia.org/wiki/George_Mackey -- wondered openly as to whether women could do top-level mathematics. In fairness to him, the women in that era were still few and below average, and one even had the temerity to whine about discrimination when the real problem was that she wasn't particularly smart or hardworking.
Moral: Even if you don't see bigotry in YOUR part of a group, don't assume it isn't common elsewhere.
At the end of the day, this was a highschool class with comments being made by highschool kids. The one comment specifically detailed in the article is an old internet meme that was largely popular in gaming circles. The teacher, the only one in this entire story that might have some small connection with the tech industry, never made any inappropriate comments or behaved in any way misogynistic at least so far as the details in the article. To call this story an example of misogyny in the tech industry is pure BS, it had absolutely nothing to do with the tech industry in any way.
Edit: More context on the comment the article mentioned: http://knowyourmeme.com/memes/get-back-to-the-kitchen
I agree that it's not necessarily an example of misogyny in tech per se, but it's absolutely a contributing factor in why there are so few women in tech -- many first experiences tend to be as the sole female in classes with socially outcast males.
To begin with the state of tech education in public schools is absolutely abysmal, it takes a dedicated student with a strong interest in tech to tough it out through the school system, rather than being encouraged to go into tech by the school system. The media portrays programmers and other tech industry professionals as a bunch of lonely anti-social misfits who are almost exclusively male and either so exceeding stereotypically nerdy as to practically qualify as autistic, or else overweight and lecherous. These two factors combined mean that the vast majority of students, both male and female, decide to avoid the tech industry at an early age because either they believe the media stereotypes or else they take some tech related classes and are so appalled at the curriculum that they practically run to other professions.
When considering a career in the tech industry, going solely by the state of pre-college and entry level college tech courses, combined with the overwhelming media stereotypes around the tech industry, is it any surprise most women decide to pursue other fields?
Also, I believe it is specifically a tech problem. Medicine and law are approaching gender balanced. Tech, though, has been getting worse over the decades.
To me this sounds like another version of the "you're doing it wrong" anonymous grumbling that the internet provides for pretty much anybody doing anything.
I'm going to keep trying to fix tech the way I think tech should be fixed. Whether or not J. Random Commenter "accepts" my analysis of the problem isn't something I'm worried about. It's a given in pushing for societal change that most people think you're wrong in one way or another; otherwise we would already have made the change.
You keep trying to fix what isn't broken while ignoring what is, just don't go harassing everyone who's trying to get things done, or get upset when everyone else thinks your nuts for tilting at windmills.
