What is the author's style in Native Roots: How the Indians Enriched America by Jack Weatherford?

Weatherford's work displays a clear interest in rehabilitating minority groups who have been misrepresented by history, particularly for malicious, racist or imperialist reasons. Weatherford's interest continues throughout Native Roots. The reader must be aware of Weatherford's bias in favor of the Native Americans. No one must ever make light of the charges Weatherford brings against European settlers not only for the death of Native American civilization (by and large) but for obscuring their central role in the history of North America.
