It is common and unsurprising for anti-Mormons to attack the character of the Prophet Joseph Smith. By doing so they can elicit fury from among their co-believers and engender confusion and hatred among the ignorant. A common tactic I have encountered recently is the argument that even if Joseph Smith wasn’t a pedophile (an accusation I have disproven elsewhere and a link to which will be in this article) they nevertheless argue that because some of his plural marriages were to people significantly younger than him those marriages were necessarily abusive by default because of the differing levels of maturity and therefore power and equality present in the relationship. In this article I dismantle this argument and evaluate its accusations and assumptions in the light of what we know of the culture and history of the era that the Prophet Joseph Smith lived in. Ultimately, I demonstrate that for multiple reasons this argument is incorrect and nothing but a fallacious act of presentism that has little to do with Joseph Smith or the times he lived in.
