"Roughly half of battered intimate partners are men, battered by women."
Is quite simply false. Other posters have already said it, but it bears repeating. The vast majority of perpetrators are men.
Yes, men are victims, but they are considerably less likely to be killed, hospitalised or subjected to sustained, repeated attacks. They are also far less likely to be in fear of their attacker, or to be financially abused, or to be the primary carer of children - which is what leads people to need and seek refuge. Yes, John- you can't state government acts until you're blue in the face, but the fact remains that women are more likely to be primary carer, and when they seek refuge from a violent partner, are unlikely to want to leave the children in his care.
There is help available for male victims - links can be found on the women's aid/ refuge sites, but it is essential that women and children victims can be given sanctuary in women only spaces.
Incidentally, I won't be asking Erin Pizzey anything at all, since she theorises that women crave the violence against them. Which is probably why all these MRAs like her so much.
