It's not actually work related. It's about their opinions.
The author of the article isn't getting shit because she's a lead developer, she's getting shit because she writes articles on gender equality in gaming. Her example persons are also having some female-centric activities.
If I write a gaming opinion piece called "Mens world: why game devs should ignore all whining women and focus on their main demographic" I'd also get a lot of angry mail and spiteful messages. If I write a followup article after such hatemail called "Ruling elite: how a small minority of females with an interest in games try to hijack the industry and suppress dissident opinon" I'd get even more shit heaped onto me.
Is this a sign that I'm harassed because my gender? Is it a sign that the gaming demographic is full of bad persons? Or is it a sign that inflammatory opinion pieces will always result in hatemail?
