This information is almost 10 years old.
But these are studies, from one decade to another, 1970's, 1980's 1990's, showing long-term evidence that women are more violent domestically than men, and one study was from 2000 showing that lesbian women are more violent than homosexual men. This supplements and concurs with the rest of the studies. Data over a long peroid of time and cross-culturally evidence is hard to dispute.
The study by Revs. Sowell http://www.dvmen.org/dv-38.htm found that "females are most often the perpetrators of spousal violence in most cultures that have been studied to date. This leads many professionals to conclude that there is something biological about violent females in family situations."
Alot more where that came from as well

The studies show that Women are just....meaner.
