I think this is all whataboutery to the actual action of rape though, meeting up the day after a night out doesn't mean they were planning anything either, its common enough. I also don't know how this 'I just think they're stupid young men' can't apply the bolded either.
Contrary to what is common belief, a lack of consent does not mean the man is guilty. Its defined in NI as:
5.—(1) A person (A) commits an offence if—
(a)he intentionally penetrates the vagina, anus or mouth of another person (B) with his penis,
(b)B does not consent to the penetration, and
(c)A does not reasonably believe that B consents.
Its very possible that there was actus reus (the action) but no mens rea (the intention or knowledge of wrongdoing). You need both to commit rape and sexual assault which is the reason these cases are often seen as so unsatisfactory, there is no equivalent to manslaughter in sexual offences.
The girl was drunk too, possible regret, misremembering etc... must be considered too. It was undoubtedly a traumatic experience for her and I feel sorry for her but traumatic experiences don't need to be caused by another person and can be a result of one's own mistakes, bad decisions can also be made as a result of trauma as you alluded to earlier retroactively withdrawing her consent, or believing she didn't when she did might have been a result of this. From my point of view a lot of mental gymnastics have to be done to not give the accused the benefit of the doubt here.
