Well the first part about who is likely to be an abuser I can see how one would argue that. But why focus on the mother about what she should be doing in a divorce? Responsibility for the children rests with both parents! Even if in the end it's often the mother actually stepping up.
I find that's a central part of the article, that societal pressire for men to look after their children is lacking. And they don't on their own measure up. There's no easy answer, and telling the mothers they are responsible for absentee fathers is too easy a take.
