No, I doubt the books have anything to do with the increase in Domestic Violence, maybe awareness campaigns are just causing more cases to be reported.

The books have absolutely jack shyt to do about violence and rape, the only acts of violence committed is when the Protagonist's past is brought up, explaining why he is as twisted as he is in the present day.

The relationship between the 2 main characters is portrayed as kinky but nurturing, a safe environment for 2 consenting (and future loving) adults.

No acts of violence are committed toward the girlfriend, she is a consenting adult, and wasn't forced to engage in any kind of sexual acts.
They practiced open communication regarding what is ok and what is taboo in the bedroom, as well as in the relationship itself, and didn't engage in anything against her will, or even anything that felt unsafe to her.

I can't read or watch DV, rape, or any kind of sexual abuse shyt, I have been beaten to a pulp by an ex bf, and I was molested as a child, and I find such story lines actually disgust me.

These books definitely did not have DV, rape or abuse themes.

If anything, the main theme that was explored is trust.
She trusted him with her body, and in return he learned how to trust her with his heart...

Some people are intrinsically sick and twisted, blaming or banning books and games won't cure them.

If a public poll can show that most of the women who read these books went on to abuse their partners afterward, then I will retract my statement.
