The Spaniards did all in their power to crush the religious spirit of the Inca. In a manual published early in the seventeenth century as a guide for missionaries, Pablo José de Arriaga offered simple advice for priests confronting idolatry. “Everything that is inflammable is burned at once,” the priest wrote, “and the rest broken into pieces.” Arriaga himself spent a year and a half in Peru during which time he alone was responsible for the destruction of 603 huacas, 3,418 household shrines, 617 ancestral mummies, and 189 field shrines.

You are right to be disgusted with Arriaga’s actions, but the US is not so different. Because of the war we started, Iraq’s cultural heritage is quickly disappearing.
