There were also the times when rape was a fact of life, like during every war ever, including the conflicts between "civilized" peoples during WWI and II.
It's all still there today in different forms. At the extreme end fraternity culture which objectifies women so totally we need to have national conversation about how rape is bad.
But there are also many subtle currents in tech that lead to an exclusionary environment. She's not invited to the bar with the guys. She's not welcome in the testosterone atmosphere of the game room (someone make another balls joke). She must deal with a number of socially awkward people who have trouble interacting with those who are different. And finally scepticism about her hacking skills. I personally participate in "boy's club" activities. I personally am awkward. I personally have some kind of bias where I expect less from female coders until proven wrong. I see these subtle currents in my own actions and experience.
And I'm not even going to get into the seething hatred outspoken women often face in the form of online bullying and death threats.
"Women need to stop whining about sexism," is a totally callous response which ignores the ways in which women are made to feel as outsiders. You know how black people faced all this prejudice in the 60's and yet some are still virulently homophobic today? I think it's kind of like that with tech where people who used to be unpopular nerds don't know how to treat the minority in their own midst with respect and acceptance.
