Maybe it's old fashioned to look for heroes in a history book. Maybe it's sentimental to focus on racist attacks against poor and proud people, like american indians and african slaves, at a beginning of a new empire. Maybe it's not literary correct to read about a writer's sources while he is telling a story.
But it sure is refreshing when history can be put in front of you in a way different than you are used to, even if you do feel yourself disagreeing on parts. People's History Of The United States, by Howard Zinn is not only a fresh account of the american history but actually worth a read.
