David J. Silverman is a professor at George Washington University, where he specializes in Native American, Colonial American, and American racial history. He is the author of "Thundersticks," "Red Brethren," "Ninigret," and "Faith and Boundaries."
His new book, "This Land Is Their Land: The Wampanoag Indians, Plymouth Colony, and the Troubled History of Thanksgiving," reveals why some modern Native people hold a Day of Mourning on Thanksgiving, a holiday which celebrates a myth of colonialism and white proprietorship of the United States.
