Robert Heinlein fanatics are the main reason I don't like Robert Heinlein.

"Well, yes, all of Heinlein's heroes were mental and physical supermen who could discuss obscure philosophers, seduce a woman, kill 20 men, and fry an omelet, all at the same time, but that's because Heinlein himself was a mental and physical superman. And yeah, some of his characters indulged in an occasional rape, but the girls always enjoyed it, so that's okay. Besides, Heinlein is the Greatest Author Who Ever Lived or Ever Will Live, and he wrote Have Spacesuit, Will Travel and Stranger in a Strange Land, so we should be grateful just to exist in the same world that he did..."

The only fans more irritating are the ones who worship Ayn Rand.
