No I am not a conservative. I have read that book, and the first time I read it I liked it a lot. I thought it was the definitive book on US history. However, I have heard from many reputable sources about the problems that the book has, and Howard Zinn himself has an obvious agenda. Regardless of ideology, a book that paints itself as nonfiction history book should be objective and unbiased. The Peoples History of the United States is undeniably biased in my opinion, and for that reason I do not recommend it except for someone's own personal enjoyment.
