Consider Mormon 5:20. After all of the violence, then the lord will remember the covenant made with them.
But reality does not work like that. Genocide survivors become atheist.
http://allafrica.com/stories/201303040084.htmlThe LDS church teaches that America's indigenous peoples were not righteous and suffered god's wrath while he cleared his special land for a new people, sweeping away up to 90% of an entire hemisphere's inhabitants beginning in 1492 (1 Nephi chapter 13). The Book of Mormon teaches of a god who brought other nations and gave them power to scatter, smite and take possession of the lands of America's indigenous peoples. It teaches of a god who afflicted innocent women, children and elderly with his wrath.
Since 1492, more people were destroyed over a greater expanse of land than anything found in the Bible excepting the mythical flood. But unlike the Bible's bronze age fables, the actual events of the past 500 years in America are confirmed matters of factual history, having nothing to do with any god.
Accepting the Book of Mormon takes this violence to a level far beyond the Canaanites. The lands promised to Abraham were about the size of New York and Vermont. The Canaanites lived in an area smaller than New Jersey. North and South America combined are larger than all continents except Asia.
Simply accepting the violent perspectives is morally condemnable. Not to mention the desensitization that this can cause to otherwise loving, caring human beings.
And it is not all in the past. The Maya people of Guatemala suffered horrible genocide as recently as the 1980s. It would be morally condemnable to liken the scriptures to the present and believe that they Maya are still suffering in fulfillment of Book of Mormon prophecies.
