I must admit that my disappointment with this book is my own fault. I read the title as "Blame Hitchens, Dawkins & Harris--Essays of New Atheism". In other words, a collection of essays by those authors. My bad.
The essays are sophomoric, in my opinion. For example: "There is some passage in the Bible that says, 'The children shall rise up and kill their parents,' or words to that effect. Yikes!" Would it have been so hard for him to actually find and quote the passage correctly? Is "Yikes" really the most thoughful commentary on it?
The author presents the book as saving our time and money. Don't let him patronize you. Just read Hitchens, Dawkins and Harris.
