There's a lot of ad hominem it throws around, which doesn't really bolster the argument. It's a catchy headline but it all depends on who you know and what you talk to them about. There are a lot of fucked up, mal-adjusted people out there, and I should know, Because I'm one of them. But enough about me, nobody has a good sampling of the human experience. There are 8 billion humans alive, and there's no way to get a representational sampling of them in order to have an unbiased view of what humans are like. There's especially no way, because you're trapped in your own human body, which bases your experience of other people. Backpacking as a 21 year old woman is way different than backpacking as a 50 year old man. So the question is, has the book helped more per than it's harmed? I don't know. There are certainly people who read it and drew the wrong conclusions, but there are people who have used it to go on to lead healthy productive fulfilling lives. To reduce the entire work down into a single word, bullshit, is reductive to the point of uselessness. Of course that's the headline and the entire article doesn't won't fit up there. The article's author goes into much more detail but even if you don't like the work, calling it bullshit needs to engage more with what level of bullshittery it is and isn't for the review to come across as anything more than an highly motivated takedown because someone in the author's life used it against them.
