Agree that it's a pretty complex issue. I posted that study because I think it's always important to look at the data rather than making assumptions, which many people do about things - immigration, for example, when the stats actually show that the reality is not what is crowed about by bigots.
I think there is an element of similarity in this instance as I've read posters on here repeatedly criticising men for watching violent porn when the reality is that twice as many women do (and I believe the stats as Google Analystics is generally pretty accurate on account of the huge amount of data it reaps which is then used to determine sex - web searches, channel subscriptions, browsing history, etc). Although tbh I'd also have assumed men were the main demographics before reading that.
Of course, as you rightly point out, many of the women who watch this violent porn have a history of abuse, so of course one could argue that it's still a product of ale violence. But sadly it's still most likely women that drive demand for this content, and in the process contribute to the abuse and mistreatment of other vulnerable women.
What seems a bit contradictory though is the finding that 'women who reported being less repressed about sex were more likely to have rape fantasies, more open to fantasy in general, more likely to have consensual fantasies and finally, they were found more likely to have high self-esteem'. I wouldn't have assumed that abuse and high self esteem went hand in hand (perhaps the opppsite), so it's definitely not a conclusive matter.
