if a person chooses to drink and as a result of their choice to drink, they cause harm to another person, they are 100% responsible for that. There can be no leaving aside of their behaviour because their behaviour is the top and bottom of it.
If I went to the pub and had a skinful, then got in my car and drove home, and on my way home I knocked over and killed someone who was walking home drunk from the pub, there is no WAY that I could successfully defend myself or reduce my responsibility by saying well, they were drunk and if they hadn't been, they would have been able to see me weaving down the road and they would have known I was drunk and they wouldn't have put themselves in a situation where I could run them over, so therefore it's partially their fault they're dead.
A woman is not causing harm to another person by getting drunk but harm is caused to her if a man chooses to rape her while he and/or she is drunk.
That is his fault. Not hers. His responsibility. Not hers. He chose to drink and to rape. She chose to drink. Not to be raped. Her choice didn't put her in that situation. His did.
If the law is now clarifying to men that women actually have to give recognisable consent - recognisable if described to a third party, that's a good thing.
It's a terrible thing that such a clarification was ever needed. We should never be in a situation where we have to be saying to men look, if you want to have sex with a woman, just take a moment to look at her and make sure that's what she wants too, ta everso.
