Query: Total disappointment

If you're hoping as I was for some convincing analysis grounded in fact, this is not for you. The book is glib; the data cited here and there do not begin to support the central argument, which we're left to take on faith. I don't let my 11th-graders get away with this kind of sloppiness in their essays, especially on such complicated topics.The book is of interest only to those who like tirades without much foundation to them.
