Silicon Valley
It exists in sort of a bubble, where women are fewer in number than they are in the general population, and more of the men are the "awkward don't have much experience talking to women" type than in the general population. Many people work long hours and have zero social life outside of work (though some of them would have zero social life even if they worked only 40 hours a week)
The spectrum from casual sexism to sexual assault isn't something you're automatically immune to committing just because you're progressive, so I don't see what being in SF rather than a more conservative big city like say Dallas has to do with it. You may be more aware of it and indignant when it is demonstrated that others have engaged in it, but that doesn't mean you'll be more aware of it within yourself.
I agree with those who suggested that money is part of this. Some women are attracted to men with money, and men with money know it. The problem with the behavior being described is that it ISN'T offensive to ALL women - some of them crave attention from men with money. There's certainly no shortage of money in the Valley.
Some men are lucky, and are able to read women like a book, and know who is interested in them beforehand, so they will never have to worry about making unwanted advances. Most of us are sadly not blessed with this, and some buffoons simply 'press ahead' with their behavior, perhaps likening it in their mind to asking a dozen girls to dance - even if most turn you down eventually one will say yes. Combine with alcohol, drugs and/or a general lack of empathy for how others feel and you get the behavior being described.
The only fix is for the women (and any men that may see it happen around them) to call it out, so behavior is eventually forced to be modified. That won't fix everything, of course, nothing will. It would at least dial down the casual 'bro culture' in SV that tolerates and enables it.
