You ignored my point. Since you (and your Church) regard simple people who cannot except evolution (or the notion that the Bible is a collection of fables and parables), why don't you just throw them all out? They embarrass you, right?
Were all those illiterate peasants in the Middle Ages evolutionists, or were they Southern Baptists?
I didn't disregard your question. Societal status has nothing to do with whether one accepts a magisterium. The fact is that authority to decide Biblical interpretation is not invested in individuals of whatever rank. Private interpretation of scripture is in conflict with Catholic doctrine.
