The American Tradition

A book I'm currently reading, Lies My Teacher Told Me, is predominantly about ripping apart America's history text books and finding many cases of lying by omission, heroification, and other non historical contents within. Here's a certain quote I find interesting:

""The US has done more than any other nation in history to provide equal rights for all," The American Tradition assures us. Of course, it's authors have not seriously considered the levels of human rights in the Netherlands, Lesotho, or Canda today, or in Choctaw society in 1800, because they don't mean their declaration as a serious statement of comparative history - it is just ethnocentric cheerleading."
