One of the troubling trends JK Rowling mentioned in the material which caused her persecution was this trend towards greater supposedly consensual violence against women in sex.
It was born from widespread porn use by heterosexual men, the growing acceptance of that and the male view of what sex is all about as a mainstream view, and the belief that masochism is one of the determining traits of female sexuality. The neofeminists added to that the idea that sex work is empowering and that being objectified in sex is also empowering.
To state any of the above causes people to call you all sorts of names as a SWERF or a prude. But there's hardly anything written today about what women might actually like in sex that wouldn't come from staged porn or that wouldn't privilege male sexuality.
Apologies for not focusing on the horrible central topic of this thread more. I do think, though, that it is this trend which makes it so easy not to prosecute rapes in the UK, and it is this trend which made the rough sex defense so common.
