Query: Yes!, it's a polemic, not history, but a good one

This book is not a history textbook and I do not think that was the author's intention. The book, or pamphlet if you like, is an argument meant to clue everyone in of the clear bias in U.S. history textbooks that teach high school students tripe (in the words of Lisa Simpson). The examples are few but well argued and it is slanted to the left and deals a lot with race and class relations. It is meant for the layman and does a good job arguing part of what is wrong with U.S. History textbooks. You will find theories on why the textbooks all seem to say the same, un-thought-provoking things, included in many of the examples.
