I agree that it could have happened in past years. But I don't think it would have.
I suspect even 10 years ago it wouldn't have been seen as a dreadful thing to be accused of.
20 years ago the attitude would have probably been far more on the "good on you, mate, bet she enjoyed it". Or "she asked for it" level. Which we know to be wrong now, but that is how it often was.
The woman would most likely not have spoken out for fear of being shamed-and definitely not to any male friends.
When I was at school, bullying was something that wasn't talked about really except in an abstract sort of detached way.
Now being accused of bullying is seen as been (rightfully) bad, but I've also seen it used in a way which is in itself bullying "if you don't do as I say, then I'll say you're bullying me". That wouldn't have happened when I was at school because being bullied would have been seen as something to be ashamed of.
We need to learn to navigate this situation where victims are believed, in a way they weren't in the past. However we also need to be able to look after people who are accused, and judged by their peers on the word of one person - which this sort of thing always would be.
I don't have any answers to this. It is tricky because it will come down to one against another every time, with strong feelings all ways - and there will be times where there is no right or wrong side.
And I think online stuff doesn't help in this way with things like the "Fifty Shade" stuff, which glamorises being "rough".
So we also need to be educating young men on this, I'm not sure saying protect them from it is going to work, but educating them.
There is no easy answer which protects all victims from abuse but also from slander (and that can happen to either side)
This is not making any comment on which side the case in point comes down on, more a general comment on how things are currently in the world.
