I don't think anyone can argue that men are the main perpetrators of DV, however there are women who get very defensive, if you dare mention the fact that women-on-men DV does exist (albeit not on the same scale). They act as though it's trying to play down men-on-women DV, and it isn't, it's just merely mentioning that men are sometimes victims. I didn't realise we weren't allowed to talk about that fact.
The most personal experience of DV I have, is that which my older brother went through with his first wife, and I'm not going to bore you with the full details, but her last attack left him close to death. It was horrific.
I have female friends who have experienced DV too, but as I said my brother's experience is the most personal to me, because you know he's my brother, my flesh and blood.
Speaking to a former friend once, we had a discussion about DV, and I said something about my brother. Her response was to say something like, "oh here we go... blah blah blah... men can be victims too. Well boo hoo, maybe so, but women are the victims more often, so I feel for them more than I do male victims."
(Now you can see why I said former friends).
Yes it's important to continue to acknowledge that the majority of victims are women, but it's equally important to acknowledge that men can be victims too. And mentioning male victims doesn't automatically make that person an MRA (as sometimes people seem to imply).
