Think of the constant mantras:
If you mention DV, someone in seconds will point out that men are victims too, and women do it too.
We're told men who try and strangle/beat up/constantly abuse their children's mother are 'good dads'.
When a man systematically murders his wife and children in the most horrific ways, (and very often then comes out a history of having been a domestic abuser) he was a 'lovely man' and everyone sadly wonders what drove him to it.
Newspaper reports often talk about female victims of male violence without mentioning their names, or implying that she just kind of dropped dead, or the violence just magically happened rather than directly stating the perpetrator's actions.
Our whole culture is steeped in it.
And we wonder why vast numbers of teenaged girls are desperately trying to find ways to identify out of being female.
