I agree the hacker scene is full of assholes.
I ask this not to argue, but because you seem both pleasant and informed/opinionated and will likely have something useful to say: what as a male hacker am I supposed to be doing about the issue in this thread?
Let's assume what I know's not true for many men - that I am not even slightly coming on to or harassing or creeping on anyone and am very polite to women personally, or abusing position over them, etc. (I used to be treated like some kind of rapist by many women for prosaic things like opening doors or walking down the street, I guess from inherent suspicion of single men - now that I am usually with my wife when I'm outside of work/home, nobody looks at me twice or gives me dirty looks, which is vastly less awkward).
I don't often see situations where women are being harassed these days, so I don't even have scope to act like some kind of gender-police hero. Nor is it always called for, that I can see; I like to reassure or express solidarity with people who are getting treated in a normally dickish way, but usually not in the form of a giant "you are a huge asshole" confrontation, which can be bad for one's career and such, especially when 'the hacker scene is full of assholes.' But if I noticed sexual harassment or implicit threats or something I would already try to make sure something was said.
So what else is there? Should I just admit some kind of privilege and say it's really bad and then I don't have to do anything else, or is there some specific thing I should be doing? Because I can't get a specific reading on what I ought to be doing and sometimes suspect in these conversations that I am just supposed to feel bad and say something submissive, which really isn't satisfying when I have honestly spent my whole adult life consciously trying to be nice and even-handed to women.
