Re: I expect votedowns
Going to preface this with two facts, which are that I'm a female in the programming industry and that my impressions are just those of my experiences personally and of female friends when we've discussed this. Putting that at the start so that people can lend as much or little weight to the following as they wish and acknowledging that it's not a scientific survey. That said, anecdote is still the singular of data so a few thoughts:
Firstly, whilst institutional sexism does exist, my encounters have always been based around a few bad eggs. Most of the people I've worked with it's not been an issue. However, those bad eggs do exist and sometimes they're in a position of power. So it happens.
Secondly, I find that it has varied by nationality and sector. Again, I'm emphasizing this is personal experience, but I have found it markedly worse in the US than here in the UK, and in turn the UK is worse than Germany where sexism seems to have largely vanished. (I know it probably exists, but I've never seen a hint of it in working with German companies). Where I have encountered it in the UK, it's been in the financial sectors and amongst sales people. The City (as they delightfully call it) still is rife with sexism. Thankfully I don't work there and don't want to. But I have female friends who have and the impression is not good. With regards Sales, it just seems to attract a lot of male-dominated, somewhat sleazy attitudes. Maybe it's the back-room deal / old boy network culture that predominates, but the Sales teams of big companies are where I've run into some truly repugnant sexism. And the only place where someone has called me "doll" in a work-place environment or told me in a meeting to make the coffee! (That didn't end well for anyone involved in that meeting including myself who was kept out of future meetings by various means).
In engineering and software departments and small companies, it's been fine. Including the USA on the whole. It's mainly those bad eggs rather than a sexist culture. And it's interesting that this survey is around online behaviour because in the workplace, the non-sexist majority have typically kept a lid on any sexist members of the team. Maybe it's online that they feel unrestrained enough to be open about their prejudices.
Anyway, anecdotal evidence without an asserted conclusion. It does exist in our industry and should continue to be chipped away at. It's about equal opportunity and meritocracy. That's the end goal, imo.
