Wamster, evidence of "intergenerational transmission of violence" is inconclusive. It is seductive to believe that violence breeds violence, but the facts don't back it up. I think folks perhaps want to believe that rapists and abusers come from "bad backgrounds," because that just gives another excuse for "othering" people with "bad backgrounds."
Rhubarb, having just come back to this thread, it does seem that you are taking challenges to your posts, disagreements with your views and requests for information to back up your assertions as personal attacks. They are not. I don't tend to wander far from this room, but in most discussion boards, it is considered very bad form to start new threads or hijack unrelated ones to whine about what's happening elsewhere.
As far as the original point of the thread, hopefully the idea that we need to be focussing on criminal profiling techniques as the key to preventing rapes has now been put aside. The real issue is ensuring that all men recognise and respect women's (and other men's) boundaries and are accountable for their behaviour. Some of that is about early prevention - ensuring boys and girls are instilled with self-respect and respect for others and challenging the views of those who already see men-are-entitled-to-sex-from-women as the default position.
