**Brigham young was the greatest con man of all time.**
Maybe a tie with Smith. But Mohamhead has them beat. So many want to have the impact on the world that Jesus Christ himself had and still has. So they come along declaring themselves to be the latest or last prophet of God. And that seems to require carefully thought out writings to give them cred with the ignorant.
I stand corrected!
Perhaps Karl Marx belongs in the group as well?
