How do you dare speak in such a sensible and understanding manner? Why don't you talk about the times where you met a jerk at your workplace and he was a jerk, and you were offended, so now every workplace ought to be filled with men full of lust because they are geeks so they have poor social skills (funny, cliches about geeks in the office are OK !). Anyway this is, of course, a joke and some of the things I have found in previous threads.
But seriously thank you for saying what other women in the office where I have been working in the past have said: there is generally no problem. I don't know where the people I have read were working, but seriously, if it's that horrible, switch jobs.
And about the thing getting out of hand, this is the internet, people circle jerk problems ad nauseum, and Hacker News is not an exception.
Sexism is a subset of stupidity and a great deal of the latter is shown here.
