This is my absolute favorite book on masculinity and I've been rereading it in the last couple of weeks so I appreciate that you've brought it to light. I think every man should read it.
I don't blame feminism for the decline and destruction of masculinity. Blame isn't what strong integrated men do. Blame isn't what a good king does, he takes responsibility for his own life and experience. Feminism may just be a product of generation after generation of lousy kings. If our fathers and their fathers had been better kings, women wouldn't have something to rebel against.
Yes, men should take advice from the book but they should ignore feminists. Pretend they aren't even there. My number one piece of advice for men who want to be better is to ignore 90% of what women have to say about the whole issue.
