I think she just inadvertently pointed out female privilege.  Society as a whole tends to look down on saying or doing anything that might hurt or upset women, which is why she's able to play that card in the first place.  It's a shaming tactic designed to make people afraid of showing dissent lest they be socially ostracized.  The problem is that you can't shame, intimidate, or ostracize anonymous people on the internet.  So that would probably also be why SJW are so fond of doxxing.
