Drink drive campaigns are targetted at a small group of people.
No, they're not. What about 'Think. Don't Drink and Drive'. Isn't that addressed to, well, everyone who has access to a car?
It's the same thing.
I really don't follow why you think rapists 'don't think like' other people.
If it were really that simple, don't you think we'd have solved the problem? Or do you think all women who are raped by men they know well, are just not very bright and didn't notice that they were going out with men who didn't think like other men?
Back before marital rape was criminalised, there was a time when it was commonplace for people - men and women - to express shock that anyone could imagine a man forcing his wife to have sex, was rape. It was a mainstream view.
That has now changed, and I can't imagine someone calmly saying 'oh yes, Dan sometimes has to force Sue, but it's a wife's duty, isn't it?'
