Being run out of towns is hardly a valid measure of the worth of the man. He was challenging established religion -- of course he annoyed people!

It's too bad, however, that we don't have those golden tablets that captures Moroni's writings, from which Smith claimed to have acquired/translated the Book of Mormon.
Let me juts say this: If the meek really are to inherit the earth, then the Mormons are at least as likely as any other branch of Christianity to become our new overlords.
