According to The Gospel of the Flying Spaghetti Monster, the deletion these noncanon articles would be a violation of FSM’s key tenets:

  “Are other [beliefs] wrong?  No they are just misguided.” – The Gospel of the FSM

It would significantly violate almost all (#1, 2, 3, 4, 5, and 8) of the commandments in the Eight "I'd Really Rather You Didn'ts!

Instead of deleting these inaccurate articles, the FSM converts should be redirected to the true teaching of Pastafarianism!
