(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 manner that Adria's been exposed.
(2) When that guy lost his job, everyone thought it was a great injustice, and that Adria should make a heartfelt apology to him. But when Adria lost her job this morning, there were no such pronouncements going the other way. No one declared, "That dude really needs to apologize to Adria for making the dick joke that eventually led to her getting let go." That's not an argument that's being made anywhere.
Ask yourself why these things are happening in one direction. In an equal world -- a balanced world -- things should cut both ways. These tactics should be used by people on both "sides". But in this instance, that's decidedly not happening.
