So if you read that book, or look into any of the research behind DV you will learn that it's not really a problem women can confront at the source because the psychology behind it is one which fundamentally views women as inferior. In the same way if someone is racist somebody from a group they hate is unlikely to meet with much success trying to change their views (at best probably getting recognition as "one of the good ones") women talking to men about why we're actually whole-arse people doesn't work very well.

Aside from trying in vain to get men to learn literally anything about why DV happens and why they can actually make a massive difference talking to their mates and setting norms for acceptable ideas about women at work/at the gym/at the club etc it's not really in my means to donate to a shelter or whatever. I do volunteer for the greens around elections.

That said, being a woman in society there's the sort of basic keeping an eye on things. Making a point to chat with neighbours, hosting drinks, sharing food etc that gives you a bit of a chance to have a network of support for people, victims tend to hide the harm believing themselves to be at fault so there's not a good chance you'll actually know. You can call a welfare check on a house if you hear a nasty fight but it's unlikely to do much.
