This is the idea that women usually hit/murder their partners in self defense or as a response to chronic abuse as opposed to men who usually hit/murder to initiate abuse.

I showed AskFeminists the downward trend in DV murder against men and so far the argument is that DV shelters and no-fault divorce gave women alternatives to killing their partners to escape abuse, and that the rate of wives/girlfriends dying hasn’t changed because unlike women, men primarily kill to control/dominate.
