That is what one woman, who considers herself to have a mild case of hybristophilia, calculates based on the employment statistics:
Regarding the "bad boys" post at AG today, I found a Canadian article stating that 33% of U.S. prison workers are women, but they account for 70% of the sexual misconduct cases. So, the extrapolated number for the percentage of women affected by hybristophilia is about 10%.

This topic interests me, because I would categorize myself as having a mild case of hybristophilia. One of the things that attracted me to [REDACTED]... he is just bad enough to be appealing without any significant drawbacks. I don't understand it, because I consider myself a highly refined, moral, and gentle woman, but I am very attracted to violent men.

Interestingly, some of my female colleagues go out of their way to [help out in] prisons in their spare time. It seems rather noble at first, but now that you've posted this article, I wonder if some of them aren't motivated by feelings of attraction for the inmates.
Being a less-than-entirely nonviolent man myself - I spent six years doing MMA-style martial arts - I've noticed that more than a few women get more than a little bright-eyed when they find out about the fact that you beat the hell out of someone. Or better yet, several someones. I also knew one woman who would get visibly excited about the possibility of being struck.

This is an aspect of female nature that those of you who pride yourself on being gentlemanly and non-violent and "I would never hit a woman" need to keep in mind. People are what they are, not what you imagine them to be, and women are much more likely to fantasize about being tied up and ravished by Nazis than having gentlemen tip their fedoras to them.
