The Mesoamericans certainly had a natural right to repel such cruel, dishonorable and greedy aggressors as Pizzarro. The situation was not uniform, however, throughout the entire Spanish conquest. Conside Mexico: as Cortes passed through mountain towns and villages, many Indians told of cruel treatment by the Aztecs. These Indians were very willing to help the Spanish conquer Montezuma. Tlaxcalan allies, in fact, were the key to Cortes' victory. With all his faults, he was much more the "liberator" than was Pizzarro.
Check out my comment #71, and pardon my misspelling of Tlaxcalans. I also meant to post to Miss Marple and wagglebee when I posted that but couldn't remember how to spell the names.
