dont worry, I know never to take any point you make as a personal accusation!
I get that you suspect some may have a different outlook on women. others on here have made over exaggerated comments on similar that the only thing they know is missionary position so obviously wouldnt understand that what these did here was consensual.
On a morality view, I think what they did was disgusting, the manner in how they treated her, the assumption that she was up for it and the way the other lads want to join in in one lad having sex. It seems they dont want to do this for their own personal enjoyment, but rather so they can boast about it and tell their mates how great they are.
But again, none of that means they are rapists for sure.
As for her, she doesnt sound calculated at all. The manner of her behaviour after doesnt suggest she was out to get them. Something happened for sure that she didnt like. Did it happen at the start, or the end or half way, I dont know. She says it was at the start. Its nigh on impossible to judge that without full hearing of facts, and even at that will still probably be impossible to judge.
Her text to the friend, it could simply be a coping mechanism. How do you tell someone how it happened? I dont know? I’ve never been in a situation like that nor heard from someone like that. I dont think there is any one way to react to being (allegedly) raped. Texts dont carry emotion, they are black and white. Who knows what emotional state she was in writing it.
