VERY interesting book.
The author posits that all children identify with their primary caregivers from birth, which is generally the mother. This is fine for girls, as girls are expected to grow up and become women and mothers. Society expects boys, however, to grow up to be men but, since men/fathers are absent from early childhood compared to mothers, boys don't naturally identify with men. Societal expectations force them to break from their mothers, and the easiest way to do this psychologically is to deny any identification with women/mothers. Because their success or failure as men rides on this break, the feminine becomes something for boys/men to fear and, as Yoda teaches us, fear leads to anger, and anger to hate. This hate--however unconscious--then colors their view of women and their relationships to and with women.
The author readily admits not all men hate women, but argues that fear of "the feminine" exists to some degree in most men. He also argues that this is part of the backlash from the straight white male community against minority groups. I would have liked to see more exploration into the origin of the societal forces that created these expectations for boys--I got the sense that it's a very chicken-and-egg story--although that's probably a book of its own.
Wimp Factor was published in 2004, and I would LOVE to see an updated edition that covers the Obama administration, the Trump campaign, and the #MeToo movement. The book's concept also dovetails with another theory I've been hearing about recently; namely, that, as we empower girls and women to be more vocal/active/participatory in all fields, boys and men are left without a clear guide as to how to be masculine, distinct from feminine. How do boys become men in a time when girls are taking part more and more in spheres that once were reserved for men?
The author uses some anecdotal evidence from his private practice, but mostly a number of psychological theories and studies to support his conclusions. (I was definitely expecting more anecdotal and less scientific evidence; the technical nature of the text reads more like a dissertation than an airport pop-psychology book, and was why it took me so long to get through what is actually a pretty short book). The book's discussion of the impact of male fear of the feminine on politics does seem to stray from the impartial. I can't think of any glaring claims or assertions which were not, prima fascie, backed up by data, but I detected a LOT of hostility in the author's attitude toward conservative politics OUTSIDE its relevance to the thesis. I suspect that will engender commensurate hostility towards these ideas from people eager to criticize them.
I don't think one book has or can answer all questions about men and women in the world today, but I will definitely be thinking about this one for a long time.
