It shows that the whole thing's a fraud.
Unless you are dense
it doesn't make sense
that we are all children of God.
Last night, in the second presidential debate, Mitt Romney said that we are all children of God. That's not just a metaphor for him. Mormons believe that god is a real person living on a planet called Kolob. God has many wives who bear him spirit children. These spirit children come to Earth as humans. So, according to the teachings of the Church of Jesus Christ of Latter Day Saints, we are literally God's children. All of us are half-siblings, all with the same father.
The only logical conclusion to draw from this particular belief of Mormonism is the fact that each couple sealed inside a temple is married to their sibling, and each Mormon child is a consequence of incest.
