Black, Mexican and White history; including Mexico's Independence day and the Underground Railro

Dr. Claud Anderson presents a better grasp on Black, Mexican and White history.

Does it really matter if we know the true dates of certain events that are now celebrated? Was George Washington really the first president of the United States? Was President Dwight D. Eisenhower's mother really black? Is July 4th really Independence day? Are we really telling the true history of Mexico? What is the history behind the Texas song? Are we representing incorrect information? And does it really matter if we know our black history?
