The majority of women's injuries in domestic violence come from reciprocal violence (both parties are violent). 80% of reciprocal violence is initiated by women.  That means that the majority of women's injuries in domestic violence comes from being hit back.  Think about that for a moment. If we prevented women from hitting men, they would be far safer.
