Kinderhook plates exposed as phony
The Kinderhook plates were a set of plates which Joseph Smith claimed he was translating, and were later found to be phony plates made by someone trying to test the mormon founder.
Joseph Smith copied Freemasonry
Mormon temple worship shares an extensive commonality of symbols, signs, vocabulary and clothing with Freemasonry, including robes, aprons, handshakes, ritualistic raising of the arms, etc. Even the symbols on LDS temple garments precisely the same the major symbols of a Freemason, which are tools of a stone mason. Where did mormonism get these?
