This is a very entertaining, well laid out, and excellently written book. The fact that the authors can get such visceral reactions from both male and female readers, judging from the comments on goodreads and amazon, speaks volumes about the efficacy of their writing style.
That said, the ideas contained in this book are ludicrous and laughable, especially since every guy, at some time in his life, has committed one of these supposed "faux pas".
The book gets two stars because it at least doesn't slam going on fishing trips or golf outings, which they call "man-cations". But playing Dungeons and Dragons is not always a warning sign of bad things. Nor is wearing corporate swag. Having facial or body hair is part of being a man. And the "Pregnant Man" comment telling men in their third trimester that its ok to exercise up until their third date? That's just mean. If I made this comment about women, I'd be ostracized from my social circle.
As a public service, let me explain what makes a man or woman undateable: poor hygiene (not bathing, combing hair, or attempting to groom), poor self-control (hitting people, committing crimes, flying into rages at strangers who have done nothing wrong, making racist comments), serious untreated mental illness, lack of intelligence, having conflicting political opinions, having a face or body type that is unattractive, and having a terrible personality. Clothing, weight, and plumber's crack can all be fixed.
