I used to be a Catholic, and although I live in Wisconsin (which has a high Catholic population, at least where I lived), there were a lot of anti-Catholic things said. Usually they were friendly jousts by Protestants, although I know in other places it gets violent. The things they say kind of tell us why, though. ‘Idol worshiper’ was one of them, as well as references to Saints and Mary. Although the Catholic interpretation of this is -not- idol worship, it is usually twisted into that by Protestants. Another thing is the whole priest=child molester thing, which is projected from the corrupt clergy onto the non-corrupt clergy and people.
