I say, rather than that apostates should flourish here, I will unsheath my bowie knife, and conquer or die. [Great commotion in the congregation, and a simultaneous burst of feeling, assenting to the declaration.] Now, you nasty apostates, clear out, or judgment will be put to the line, and righteousness to the plummet. [Voices, generally, “go it, go it.”] If you say it is right, raise your hands. [All hands up.] Let us call upon the Lord to assist us in this, and every good work.I say, rather than that apostates should flourish here, I will unsheath my bowie knife, and conquer or die.

I first heard this quote as a 20 year old missionary. But though we don't hear it in church meetings, I think it represents a covert pattern of thinking in the LDS Church: a disturbing correlation between Mormonism and violence is explored in one of the Church essays, "Peace and Violence Among 19th Century Latter-day Saints." The essay covers violence against Mormons, and also retaliatory violence by Mormons. I'll cherry pick a quote: "In addition, Mormon vigilantes, including many Danites, raided two towns believed to be centers of anti-Mormon activity, burning homes and stealing goods.22 Though the existence of the Danites was short-lived, it resulted in a longstanding and much-embellished myth about a secret society of Mormon vigilantes." But I might be wrong.

I recommend a good article in the "Wheat and Tares" "DezNet and the Latter-day Saint Vigilante Tradition.
What is the deal with this?
