Yup. Mormonism was set up by a con man called Joseph Smith. He found gold plates with the story of how the last tribes of Isreal sailed to America and became/converted the native Americans. He had special stones to translate the plates etc.
But its not the point really, because freedom of religion.
There are Catholics who say Protestants are not Christian, and vice versa.
Again, not the point, because it is freedom to believe.
And Mormons do vote in elections. It is JWs that don't.
Surely this will hurt them at the ballot box.
