You know, if she wasn't such a publicity-seeking hypocritical douchebag, I'd take your point. However, her pattern of behavior clearly shows that to be the case (she was tweeting sexual innuendos
while at the conference).
So I think her MO was not "I feel vulnerable because some guys are making me uncomfortable, this is wrong, I'll do something about it". It was rather "I have a bully pulpit from which I can demonize some schmoes and raise my status at the same time, so I'll do it". Therefore the discussion of her over or under-reacting is moot - this was a publicity stunt that ended up backfiring on her.
While I regret people being fired, I can't help but feel that her ultimate downfall is deserved.
