I disagree Vestal. The more people post about their shit relationships, the better.
The trouble is that when you're in it, it's hard and some people will say the wrong thing inadvertently. When you get out, some people will say the wrong thing.
The people who understand DV are either trained professionally how to speak about it, or have experienced it themselves. It's a closed world, and people who haven't experienced it or been trained professionally on the whole simply don't understand it, it's insidious nature, how it acts on your psyche, how living with it - for a long or short time - can destroy you, how you plaster on a smile and pretend everything's fine "you're just a bit tired/down today but no reason......."
People are raw. Their emotions are right there, if you prick them they will bleed.
So yes, a call for greater sensitivity and more a general population-wide knowledge of dv would both help a great deal, and I too think young teens would benefit enormously from some discussion, at least, on the subject. I want it to be much better empathised with in our whole population, and I would like more funding for projects and organisations which work at the sharp end, with the victims, much more help and support available.
We can't stop people from expressing their views, whether they are crass and ill informed or knowledgeable and kind. But we, as a community, should try to ensure that any victim who comes here for help and support and advice gets it, and that the lone voices (and there are pretty few of them overall) are drowned out.
I know a single voice perpetuating the views the abuser has been inculcating into their victim can be more cutting than 1000 voices speaking kindness and support, and I have no real idea how to stop that as things are. I don't think there is anything we can do to stop it happening, myoriginal, and I'm really sorry for that. All we can do is what mainly happens on Relationships already.
I know it's not enough at the time, and I think your wish that people who have little or no knowledge of dv themselves to not comment like that is entirely understandable, but we can't stop them, we can only try to help clear up the mess they leave in their wake.
