There are two really interesting, and frankly devastating, double standards at work here: (1) We all know Adria Richards's name. We know all about her. Her personal address has been spread. Things she wrote in the past have been used against her. But we don't really know anything about those guys. We know who they work for and what they look like, but there's been no widespread effort to expose them in the same manne…
(2) There is a direct set of causalities leading from Adria's actions to the first firing. It wasn't (IMO) Adria's fault that he was let go, but it was a direct byproduct of the way she dealt with the situation. On the flip side, Adria did not lose her job because that guy made dick jokes. The causality there, while perhaps still arguable, is far more uncertain. There are numerous other ways Adria could have dealt with the situation which would not have resulted in her being fired.
Furthermore, regarding it being a double-standard in general -- Had Adria been a man, I suspect that both your #1 and #2 points could still have been true given the nature of the events. But hypotheticals are tricky, and in either case there would probably be numerous double standards at play. But the divisiveness of how it was handled makes it hard to address the real issues, which is highly unfortunate.
And lastly, to be clear, I could never, ever condone the hurtful, misogynistic, vitriolic backlash against Adria that we saw. I'd like to believe that much of that was from the froth-mouthed fringes of an otherwise reasonable community, but nonetheless I do wish there were a lot more being done to address that part of this debacle. I myself flagged a Facebook comment, but gave up when nothing really came of it and hurtful comments started coming into my own message inbox.
