Do a quiz of 10 people you know and ask them if they would prefer their mum/sister/daughter to be raped or burgled. I would be very surprised if anyone said 'oooh that's hard, the impact on the victim is comparable isn't it?' 
I don't know why it didn't occur to the judge, in her last case, that she's mostly seen trials where the rape was fairly unambiguously rape, with 'just' the clouding issue of how much alcohol had been drunk. Why she didn't sigh a deep sigh and appeal for women who had been raped by husbands / friends to be believed too, for those cases to be brought in front of judges too.
There was a story on mumsnet told by a woman of her experience on a postnatal ward. The partner of a woman who had just given birth was in the cubicle with his partner. He wanted sex with his partner. She had just given birth, and did not. He climbed on the bed and did it anyway. In a ward with just the curtains closed, with staff around. Everyone heard.
More education probably wouldn't have stopped him being an abusive bastard. But in a world where rape of your partner was totally socially unacceptable, someone would surely have phoned the police, and the evidence of all those witnesses would have been enough to put him away.
As it was she went home with him to a life of DV, no doubt.
If we as a society close our eyes to the rape of vulnerable women we only increase the chances of 'sensible' women who've taken precautions being raped. Because we create the culture, as OP said, of male entitlement. A culture it is incredibly hard for a man to realise he is part of, no matter how lovely that man is.
My husband is well aware of my history. There have been many times when the way he has behaved has upset me. Tiny things, a look, a touch, but done in the 'male entitlement' theme. He was devastated at first to realise he behaves like that, and had never had call to examine his behaviour before. Why would he? It's the model we see all around us in everyday life.
My husband wouldn't rape me. I know this, I know what absolute trust is. But he had still been touched - shadowed - by the culture we have around us. That made both of us deeply sad. People in positions of authority should be seeking to address and challenge that culture. Not tinker at the edges repeating mundane warnings we've all heard before, that mask and hide the soul of the issue.
