Slate is running a long but gripping story about a Mormon historian, D. Michael Quinn, and his excommunication and subsequent inability to get an academic job after he began to uncover some uncomfortable truths. You see two sides of Mormonism: its diverse and often questioning lay members, and its total authoritarianism. This is straight out of Dostoevsky, and it's from an address given by Mormon Apostle, Boyd Packer:
There is a temptation for the writer or teacher of church history to want to tell everything, whether it is worthy or faith-promoting or not. Some things that are true are not very useful.
The more you learn about Mormonism's relationship to "truth", and its relationship to "power", the better you understand where Mitt Romney is coming from. And where he'd take the rest of us as president.
