You wrote: I notice even I reserve most my anger at these two young women and it's the 100 plus disgusting men who are the problem. I don't know why even liberal minded women can default to this thinking.
It's probably because you recognise that the women have agency and that it's their choice to do this, and they don't HAVE to let 100 men do the things you describe. But you probably feel frustration rather than anger, that two women would let themselves be debased like this and no one is helping them or stopping it. I say "helping them" because I think that you, like most people, recognise that there is something deeply, deeply wrong with this scenario, even though the women are acting from free choice.
If I was their family or friends, I'd be very worried about their mental health, that there is something very wrong psychologically to do this. I'd be worried that they are a suicide risk, either now or from the future consequences. I wonder if it would be possible for a family member to section them, on the grounds that this is extremely abnormal and disturbing behaviour. I would certainly be looking into it, if I was a parent of either of these young women.
I feel very, very sorry for the two women. Clearly something is not right, and they will have to live with the consequences and memories of these episodes forever.
