To repeat: You found it on the Internet, so it must be true, right?
Look at some of the other neat things one can find on the Internet:
1. John Lennon was assassinated by author Stephen King, who acted under orders from Richard Nixon and Ronald Reagan. You can buy the booklet Stephen King Shot John Lennon at The truth about John Lennon's murder.
2. The Apollo moon landings never happened. The whole thing was a hoax. You can buy the video at www.moonmovie.com.
3. In the 1970s, an inventor developed an electric automobile engine that produced 40 times more power than it drew from the batteries. It, and a number of other free-energy devices, have been suppressed by powerful interests in industry and government. You can buy the books and videos at www.free-energy.com.
Now we find that Mormonism is based on a belief in humanoid extraterrestrials from a distant star, among other weird things. (I especially like the part about Mormons "performing secret temple rituals with themselves and the dead." It sounds positively ghoulish.)
By the way, do you have a link to the web site where you found all this fascinating truth about Mormonism?
