I'm sure those who do not wish to examine rape culture and who think that, by definition, all feminists are man-haters believe this book is a screed against men and masculinity. Harding is proving the OPPOSITE, in fact. She goes out of her way on several pages to explain that feminists believe men are NOT monsters and animals. This is why the basic thesis of rape culture--that it is women's responsibility to defend against rape, since men "can't help it"--is virulently ANTI-man.
Since I cannot write more eloquently or with the same cheeky and pointed wit Harding uses to great effect, I'm merely state that this book is thorough, insightful, and justifiably angry at times. I myself was angry when reading the book--not angry at Harding (though, naturally, I disagreed with her on some points, most notably on the concept of women and self-defense) but angry at the rape culture we have so long allowed to exist.
On a personal note, I've seen examples of this culture in sports so often as to be cliche. I'm not speaking of rampant sexism (though that is a cousin to rape culture, obviously) but rape itself. The notion that the star football player "gets the girl" as a matter of course, her feelings notwithstanding. The constant references to female cheerleaders as mere sexual objects to be used and discarded by men at the males' pleasure. And on and on and on and on.
My writing partner--a smart, savvy, witty and fun woman who constantly challenges me--and I have discussions on this topic frequently. We stumble over wording and how best to express the complex concepts at play. Harding's book does an excellent job of providing the reader with language with which to grasp the subject more cleanly.
So, if the idea of someone using the term rape culture offends you--"look, another bitter, angry woman lashing out against men" (Harding is married to a man, if that means anything) then be brave and tackle this book. As Harding states early in the work, "the problem is not that some guys don't get it; it's that some guys don't want to hear it."
