One can argue against what she did and not be a "mysoginist man-privelaged pig". (<--- I've seen women write that against people who spoke against Adria Richards)
There were and are a lot of people who see this issue through exactly one lens: is the man right or is the woman right? They caught hold of this issue and made it part of their long battle. This issue got reposted to those various blogs and subreddits that represent those armies. (And they each monitor the other so summoning either army summons both.) I suspect that, had those armies never been involved, neither person would be fired today. Not that those armies care. The two people who got fired were acceptable casualties in their war on The Other.
Ugh, this comment turned into pop-psychology, sorry.
