I found a brilliant quote that explains the fat delusion and why we can't stand it. “People don't want to think. And the deeper they get into trouble, the less they want to think. But by some sort of instinct, they feel that they ought to and it makes them feel guilty. So they'll bless and follow anyone who gives them a justification for not thinking. Anyone who makes a virtue - a highly intellectual virtue - out of what they know to be their sin, their weakness and their guilt... They envy achievement, and their dream of greatness is a world where all men have become their acknowledged inferiors. They don't know that that dream is the infallible proof of mediocrity, because that sort of world is what the man of achievement would not be able to bear”  -Ayn Rand Atlas Shrugged
