Conquistadors: The Rise and Fall

Again, an ad nauseum story of the oppressed and the oppressors. Really? The hollowed halls of academia produces their opinion through modern "presentism". After countless attacks on European cruelty and dominance there is scant,as in zero, criticism of the cruelty and barbarism of the Aztecs, Incas and the Mayans . These cultured and advanced people routinely attacked and enslaved other tribes while commiting acts of cruelty like cutting out the beating hearts of their victims. The Catholic chirch is viewed as enslaving these tribes as opposed to stopping cruelty. National Geographic please present both sides of this debate!
