It’s not that I think it’s a bad book, or an unimportant idea – it’s that I think he could’ve been more succint with the delivery.

Also, my own (albeit limited) experience has been more shades of gray and subjectivity than he seems to convey in his book.

Zero tolerance seems alright if you’ve got a perfectly tuned asshole detecter; I think I get this type of judgement wrong frequently. So while an asshole enabled perspective seems useful, I’m not so sure I’d trust a rule.
