Welcome chickens. 
I'm another one who believes DV is one of the most pressing issues affecting women today in the UK. It affects women who haven't been a victim of it too, because of the effect DV has on the wider society.
75% of households where a child is abused has DV going on as well. Tackle DV and a significant proportion of child abuse will be dealt with also. Linked into this is the issue of children being made to continue contact with abusive NRPs.
The acceptability of 'low level' DV (financial abuse, emotional/psychological abuse, a shove here, hassling about sex) permeates society and affects all women because it reinforces the notion of male superiority. It also feeds into the rape myth culture.
DV is about entitlement. People who feel entitled to beat up women often feel entitled to behave in a superior manner in other areas of their lives too - whether it's parking in a disabled spot, dropping litter, fiddling benefits/taxes, etc.
DV is bad for society as a whole. I think that's an important point to make if we;re going to get the wider society on board with the campaign.
But it's particularly bad for women, of course. Said abuser will get fined for parking in a disabled bay (if caught), possibly imprisoned for fiddling benefits/taxes, but he probably won't even get a caution for giving his wife a black eye. What sort of message does that send?
