Interesting that Forest seems to be linking promiscuity (I assume consensual sex with many partners) with harrassment/assault (non consensual sexual touching, comments). That seems very common.
I think as a nation we have very very little understanding of consent. The is so popular I think, because it's never been a clear idea in many people's heads.
I was amazed when I joined mumsnet because women here could explain really clearly what consent was.
to them - they totally changed my understanding.
That poor understanding of consent enables (not causes) harrassment/assault being normal, and a public (male) reaction that it's "just one of those things" or "any one of us could be accused etc"
I'm fairly sure the adult males doing the harrassing/assaulting have a perfectly good understanding of consent, to be clear.
