JUST TELL THE TRUTH REGARDING U.S. HISTORY---STOP TELLING OUR CHILDREN LIES

After 15yrs of researching U.S.history along with Native American studies, I was outraged. As I read 5 of the most popular U.S. history TEXTBOOKS, used to teach our children, I was shocked. Who is responsible for the content of these LACK OF HISTORY TEXTBOOKS???
I read hundreds of documents, journals, letters, and treaties, all found in the Library of Congress. Page after page revealed the truth about the SINS of our forefathers. Shocking, heinous acts that no one speaks of , moreover not found in any U.S. HISTORY TEXTBOOK.
Example, Columbus sailed the ocean blue; that is the only truth about COLUMBUS found . in U.S. history books. Columbus was a slave trader and a pirate; he implemented the slavery systems throughout the Caribbean. His finding of an uninhabited NEW WORLD HAD A POPULATION OF 16 million people. Columbus took into captivity strong young Native men as replacements for the SLAVES that died at sea. He offered up young Native women, to his men to fulfill their carnal desires. These young women were forcibly raped until death rescued them. Columbus ordered the slaughter of the remaining Natives. The infants were killed separately, as they were chopped into small pieces and fed to their dogs and any other livestock..... Why is COLUMBUS HONORED or CELEBRATED?
This is only one example of a plethora of convoluted tales and lies we call U.S. HISTORY.
