I have no doubt that sexism exists in this industry; I've seen it. And it does need to be addressed, in a very serious way.
But on the other hand, this started when someone made a crude but not (at least to me) harassing or sexist remark. Maybe as a male, you'll think I'm blind to such things and disqualified to judge them as "not harassing", and I actually kind of get that view--I haven't and can never live on the other side.
But I still maintain in the realm of sexist things that go on, this one was hardly a blip. And the chain of events that followed is nearly unbelievable.
There's no reason two people had to lose their jobs and have their names dragged through the mud, there's no reason two companies had to have their reputations sullied, there's no reason anonymous internet bullies needed to direct their bile towards Adria and women in general, and there's no reason any site needed to be hacked or DDOS'd.
Seriously, one loud distracting noise at the right moment and everyone's life would be better off.
