The remaining Mormons are right where the gerontocracy want them--believing the thinking has been done and their only onus is to obey.
Man has the ability to reason. The brain can take any information available, absorb facts from exploration, and then find ways that this data, these particulars, relate to each other, and let the cerebral cortex form a whole. A whole that is a whole lot greater than the sum of its parts.
Or, you can be a Mormon. Let your leaders do the job your brain was supposed to do. Then you get a hole instead of a whole. A void. An emptiness.
And you can allow them obediently to fill this cavern Mormons have carved in your soul with Canons that do not hold up to scrutiny, the feeling of never being righteous enough, belief in civilizations that did not exist, prophecy-less prophets, and with bigotry instead of reciprocity toward your fellow man as one's spiritual receptacle (Hole) is continually stuffed with arrogance and ignorance and a desperation to feel superior.
The more you adapt your self to mormonism, the more you distance yourself from your own humanity.
Mormons are right. Their thinking has been done. Just not well.
