My guess is that it's a weird elitist reactionary anti-capitalism. Protestantism is how the masses justify gorging themselves on the produce of American capitalism. It's what the hill people and the suburban psychos believe in. Catholicism is refined, has a millennium of culture behind it. They worship in great basilicae, not dirty shacks. They actually follow some rules, not arbitrarily pick and choose what they believe in. Catholics aren't so full of themselves that they think they can directly speak to god (unlike those silly prots), obviously you need a priest and some incense to talk to god.
