“LDS was preserving in its members the **Christian norms** “
I don’t think you know what that phrase means.
Social relations, treatment of others, etc. I am NOT referring to polygamy of which the main line LDS had long purged itself. I also understand that to the fanatics it is impermissable to ascribe ANY good features to Mormonism and if the Mormons believe in and enforce heterosexual monogamy then either heterosexual monogamy is wrong or it is wrong for Mormons to subscribe to it. Discussion with such people is unprofitable, a mere stirring of the air.
You don’t like Mormons, do you?
