Huh? Nice try, but that's not even remotely true. The data on lesbians is inconclusive as to why that is the case, but it seems to be correlated to a high rate of themselves having been abused as children.

The report repeatedly talked about working-class men being more attached to "traditional" gender norms. The sex part is implicit in that.

I don't understand your last question.

The research usually has been done with mostly white, middle-class lesbians who are sufficiently open about their sexual orientation to have met researchers seeking participants in the lesbian community. Subsequently, these findings may not apply to women who are less open, less educated, or of other ethnic backgrounds.

Why would a lesbian batter another woman? Lesbians who abuse another women may do so for reasons similar to those that motivate heterosexual male batterers. Lesbians abuse their partners to gain and maintain control (9). Lesbian batterers are motivated to avoid feelings of loss and abandonment. Therefore, many violent incidents occur during threatened separations. Many lesbian batterers grew up in violent households and were physically, sexually, or verbally abused and/or witnessed their mothers being abused by fathers or stepfathers (6,7,14).

Domestic violence is commonly referred to as intimate partner violence (IPV)

Eighty-five percent of IPV victims are women.

A woman is beaten every 9 seconds.

Every year nearly 5.3 million incidents of IPV occur among U.S. women aged 18 and olderI

PV results in nearly 1300 deaths and 2 million injuries every year in the United States

More than 3 women are killed by husbands/boyfriends everyday

Women aged 16-24 are most likely to be victimized by an intimate partner

Women are 5 to 8 times more likely than men to be victimized by an intimate partner
