What I know about the LDS church and polygamy could fill a thimble. That being said, the concept that a man can “wed” a child is disgusting. I don’t care what type of scripture the man twists to “justify” his need for young girls... a cult IMHO.
Mad Mo is not amused with your lack of tolerance for diversity . . . and it's not like he molested Aishia when she was only six and they married; he waited three whole years until she was nine just to give her time to grow up. Girls did mature younger then, you know. [If anyone can't tell whether this is sarcasm without a "/s" tag, I'm worried.]
Several of Joseph Smiths plural ‘wives’ were 13-16 when he married them. Several others were still married (and living with) their legal husbands as well.
All of this shares the same history and doctrine as SLC Mormonism, except these people continue to practice what Smith taught rather than give it up for statehood.
