Aztec Empire
While the Spanish Empire was brutal in their treatment of the Aztecs, the Aztecs were also brutal and monstrous in the treatment of their own people. According to Aztec beliefs, one of their gods, Huitzilopochtli, wanted to be fed freshly harvested human hearts. In 1487, the Aztecs recorded that they sacrificed 84,000 people in four days.
I'm not sure where or how, izismile gets his facts... well, not facts really, leftist propaganda more like it. As in, Confederates raping "millions" of African-American women and, too, the items you mention as well as many others. Columbus a 'conquistador'... seriously.
Post entertainment, entertaining pictures, etc., not skewed takes on history in support of a Howard Zinn view of the world.
