I found the book revolutionary.
Not so much for the analysis of abusive men, and their behaviour - and if anybody who hasn't read it, and is wondering the question "Why does he do that?" is directly answered, it it- it's because he can - but for the assertion that society as a whole is complicit in enabling abusive men.
I find there's very little understanding of the dynamics of abuse in society as a whole, and that when female victims of abuse speak up, they are disbelieved, dismissed, or their concerns are minimised.
Certainly, in my personal experience of abuse, this has been painfully evident- the abuser I'm referring to is the type referred to in the book(sorry, it's been a while since I read the book, I can't remember which one!) who likes to surround himself with women and play them off against each other. I've had quite a lot of flak from various of his female emissaries friends "who can't understand why I won't talk to him". I've had to suffer various acquaintances becoming great friends with him "because he's such a nice guy".
I'm also witnessing a friend going through the same thing- even though she publicly disclosed the abuse, she's been pretty much shut down and shouted over by (mostly female) friends of the couple, who only saw his nice side, whereas she often came over as a bit of a flaky wreck (she had serious anxiety issues, undoubtedly exacerbated by the abuse).
This is why I think everybody- women and men- should read it.
