FYI, Catholicism isn't a "Cafeteria Style" religion. You don't pick and choose what you agree with or disagree with in the church.
Actually, that's how all religions work. They may teach otherwise, but in reality there is nobody who is a "full fledged" believer of everything the church teaches. How could there be? The church itself doesn't always agree on what and how to teach. I'll agree with one thing, you don't choose to agree or disagree. It's just that people do disagree with certain aspects of what the church teaches.
It's like Texas Hold Em - you're either "all in" or you "fold."
That's what Obama bin Laden taught about Islam. Truth is that you're positing a false dichotomy. A person can be Catholic, but disagree that the Eucharist becomes the actual body and blood of Jesus. Just because the church teaches it doesn't mean that people will automatically believe it. That doesn't make them any less Catholic.
Examples of people who claim they're Catholic - but have folded on the birth issue, for example - Pelosi, John Kerry.
You really are an extremist, aren't you?
