Juan Cole itemizes ten Catholic teachings that Rick Santorum and a lot of other political figures reject while still professing their unyielding Catholicism. And I don't think it's at all wrong to think for one's self and reject a teaching with which you disagree. The problem is when you reject some, embrace others…and insist those others are inarguable because the Catholic church supports them. You know, either you believe the Pope is infallible or you don't. You can't insist he's infallible on alternate Tuesdays and then go the other direction on other days.
