Who are Midgets from The Gospel of the Flying Spaghetti Monster and what is their importance?

Henderson makes a number of offensive and politically incorrect references about "midgets" (even that derogatory name itself) and has a disclaimer suggesting the Gospel be kept on a high shelf so as not to offend them. He says midgets are short as they get the most touching from the FSM's appendages. He also claims the first man created by the FSM was a midget, and all his descendants were outcast to the Antarctic and eventually became penguins. As the population grew, the FSM wasn't able to keep his appendages on everyone, hence the population grew taller.
