Outside of Silicon Valley women are usually treated well and as equals
Meh, I've witnessed awful treatment of women in the industry and never worked anywhere near SV.
Remember that stat, that 25% of women in colleges have been sexually assaulted? How initially it seems unbelievable because, hey, you wouldn't, and I wouldn't, and most men you know wouldn't, so how can that be?
The reason it's likely true is that it doesn't a huge proportion of men to be assholes for a disproportionate number of women to be affected. If, say, 2-5% of men in college think it's OK to touch women inappropriately and non-consensually in environments in which they can get away with it, and you assume each of them gets away with it, and so assaults multiple women, then, wow, you're up to 25% of college women being sexually assaulted pretty quickly.
And the same is true in businesses. Leaving aside institutional and structural problems - which exist everywhere - it doesn't really take a lot of male employees to be assholes, showing a level of disrespect for women they'd never show to men, for women to be disproportionately affected.
One office I worked for had such a person. As in every male member of the programming team knew he hated women, and that the extremely qualified, hard working, smart woman working with him was being treated like shit solely because she was a woman, and neither young nor blonde enough to make him at least be chivalrous to her as compensation.
To my and my coworkers shame we never did anything about it. We didn't talk to him about it, we continued to treat him as a - distant, perhaps - friends. We didn't talk to management about it. "G is strong", we told ourselves, "She doesn't put up with his bullshit", and, well, yeah, but bullying is bullying, and working in that environment wears down the strongest of all of us.
It's getting a lot of press in SV right now because SV is the hub of the tech industry, and has sizable number of progressives involved in it. But the idea it's limited to SV is absurd, that'd be to assume either that base human behavior (because there'll always be sexism) somehow is under control elsewhere, or that management skills have developed to a remarkable level outside of SV.
