SURE it was!
fact that after some years of peaceful coexitance after the initial issues and some internal struggles within the LDS, leader Sidney Rigdon pronounced:
hat mob that comes on us to disturb us, it shall be between us and them a war of extermination; for we will follow them until the last drop of their blood is spilled; or else they will have to exterminate us, for we will carry the seat of war to their own houses and their own families, and one party or the other shall be utterly destroyed..."
Had nothing to do with the Missouri troubles or starting a small war. It's all those damned protestants, the mormons were just foolin' around playin' army...
Seems the fault was two sided no matter who you are.
