Hard data about women being as violent? Here's a start:

Here's a taste of what you will find there:
Archer, J. (2000). Sex differences in aggression between heterosexual partners: A meta-analytic review. Psychological Bulletin, 126, 651-680. (Meta-analyses of sex differences in physical aggression indicate that women were more likely than men to "use one or more acts of physical aggression and to use such acts more frequently." In terms of injuries, women were somewhat more likely to be injured, and analyses reveal that 62% of those injured were women.)
World famous researcher, renowned journal, important message.
And exceptionally nice cherry picking. You didn't think I would read did you?
From your link:
Aizenman, M., & Kelley, G. (1988). The incidence of violence and acquaintance rape in dating relationships among college men and women. Journal of College Student Development, 29, 305-311. (A sample of actively dating college students <204 women and 140 men> responded to a survey examining courtship violence. Authors report that there were no significant differences between the sexes in self reported perpetration of physical abuse.)
You DID notice the difference in the figures for the first "study" here right? Women questioned 2 to 1 compared to men and wow, the number of incidents equal?
It gets better though:
Arias, I., Samios, M., & O'Leary, K. D. (1987). Prevalence and correlates of physical aggression during courtship. Journal of Interpersonal Violence, 2, 82-90. (Used Conflict Tactics Scale with a sample of 270 undergraduates <95 men, 175 women> and found 30% of men and 49% of women reported using some form of aggression in their dating histories with a greater percentage of women engaging in severe physical aggression.)
Here again, a 2 to 1 ratio. Is that the only way they can get equal numbers? Something is wrong here.
Bernard, M. L., & Bernard, J. L. (1983). Violent intimacy: The family as a model for love relationships. Family Relations, 32, 283-286. (Surveyed 461 college students, 168 men, 293 women, with regard to dating violence. Found that 15% of the men admitted to physically abusing their partners, while 21% of women admitted to physically abusing their partners.)
What is it with this 2 to 1 ratio anyway? Got to even those numbers out for the resulting data somehow I guess.
Interesting thing is they used this 2 to 1 ratio for each of these studies......well, not each of them. Some of the studies employed a 3 to 1 ratio. 3 women compared to 1 man responding and then they reported the results as if it was an even response ratio?
Oh, you may need to know. I'm a senior engineer for a research and development group for a major defense contractor. I have an extremely thorough understanding of hard data and how it can be manipulated.
Let's try starting with studies that utilize data gathered from the same number of respondents from each gender pool.
You wouldn't want to try to employ skewed data now would you?
