sabrina, it seems from the link you posted that women attackers are a very small minority compared to male attackers. Also that women are more likely to be prosecuted for violence. This disparity in treatment worries me. then there's the problem of scale, male violence is much more often more physicaly damaging than female violence.
Men are attacking men too, which says to me that the problem is male violence, not just male violence against women.
I think you're right when you say that the dv against males stats seem overstated. Also, I felt the film was suggesting that women were to blame for that 40%, which is misleading.
I just feel uncomfortable at discussions about dv being reduced to who has it worse.
