Mormons: why is there a demon named Mormo in the Satanic Bible?

In the Satanic Bible there is a demon named Mormo. One letter shy of Mormon. The Satanic Bible was not written by a Christian but by a Satanist saying that it is so. Mormo was the king of the living dead. Mormons are obsessed with the dead. There's also a story of an Irish goddess named Mormo who bit children that misbehaved. I'm confuessed as to why a Satanist would insist that Mormon or Mormo was a demon.
