The article states that:
Men between the ages of 18 and 24 with high school diplomas are most likely to be arrested on suspicion of domestic violence in Boulder County, according to a recently issued study of police reports.
Yet later in the report, it quotes Malsam:
''The main thing that causes domestic violence is the patriarchal nature of society,'' Malsam said. ''We just need to change society's belief that males are omnipotent.''
The theory that patriarchy causes domestic violence is one of a number of competing theories that try to explain domestic violence. It's not the one I subscribe to, as it does not explain the equal rates (not injuries) of domestic violence in heterosexual couples between men and women, or the prevalence of domestic violence in lesbian couples.
