What has this got to do with women? Anyone could have found those jokes offensive, whatever their gender. And no-one has the right to protection from being offended, whatever their gender.
Misogyny is kind of like porn: "you know it when you see it". There is a simply an undue level of hatred for Adria which is correlated to her gender, I think in large part because she is an outspoken feminist.
A lot of people in this community would very much like outspoken feminists not to exist (check the comments here or on Reddit anytime a post about women in tech goes up).
Another way to look at it: I can't imagine this chain of events would have gone down if a man pointed out a lewd joke at a conference.
The whole thing really smells like a feminist backlash.
I'm trying to be more outspoken about gender bias I encounter in the workplace, but incidents like this are a terrifying reminder of why that can be dangerous.
A few months ago I posted about an inappropriate comment someone made to me at a hackathon and got lots of advice (on this forum) to publicly out and shame the person. Seeing that my company could have come under attack for that is a reminder of why it's dangerous for women to speak out.
There's been sensible debate and abuse. There may be an overlap, but they are distinct reactions. If you challenge someone, you invite them to challenge you back (I hope she's not terrified by disagreement). But abuse and threats are entirely separate, and seem to have come from people beyond the industry, e.g. anonymous. Lots of trolls on the net are just looking for a fight and gender politics fades into the background when you have a large number of people on a hair-trigger, willing to use any language at their disposal that they can make fit the target.
She chose public justice for all, including herself and anyone she represented in that context. That works both ways, regardless of gender.
