Query: Stupid book itself..

Before reading this book, I personally agreed with the view of the author - That's why the title sounded ingriguing to me at first.But reading this book was just annoying to me. His voice is too subjective, biased and extreme... so it lost its power to persuade people - even it drove me to the opposite direction. And also I think he is not a good writer; he needs to refine his writing skills, at least.I decided to stop reading this book in the middle 'cause I didn't want to waste my time any more. Although I re-sold my book back after that, I personally recommend you to save your money and time.
