I think there is some merit in what GG has said also.
The current judicial system is not working & rape is nigh on impossible to prove sadly. There was a very active thread on the recent Ulster rugby trial & a lot of old rape myths were trotted out; there was outrage at the way the trial went. We discussed an alternative to 'rape' as a charge as the wording of the law is something along the lines of the belief of having consent.
As in the Ched Evans case where on appeal he was found not guilty, imo this can be interpreted as the jury believing that he was stupid enough to belief that he had consent to have sex with someone he has never spoken to (& she didn't even know he was in the room I think), although most reasonable people wouldn't think this.
I thought rather than GG saying marital rape wasn't that bad she was highlighted that all unwanted sex was rape. I also think there is a difference between a rape situation where someone hasn't given active consent & gone along with it & a rape situation where the victim is held down by force & has other physical violence in addition to penetration. Levels of trauma suffered will be different from person to person for the same experience so I don't know how sentencing would be decided to each situation. I don't think it's minimising rape, but having categories may help prosecutions to be made. I do understand that it may seem like top trumps which could be unpalatable.
Another problem seems to be that the public can't seem to reconcile e.g. nice boy, well brought up and successful sports player with rapist on a par with a stranger in the Park scenario.
Primarily, I think education is key to changing societal attitudes & active consent encouraged. The current system for prosecution is not working. I think a year ago I would probably have been outraged at this by GG but my thinking has changed in light of some recent trials.
