Eh, personaly I know very few catholics who consider the bible to be infallible. That argument usualy comes from people who never attempted to properly study it, or protestant pastors who reign in people by convincing them that the bible (IE their personal interpretation of the bible) is infallible and everyone is going to hell for not listening to him. Faithful or not, considering the bible, a document formed out of dozens of different testimonies and accounts, and subjected to multiple translations and interpretations through a period of more then a thousand years, as infallible, is a bit foolish.
I'm not saying that the catholic church hasn't profitted from its definitions and interpretations of the bible, or that its doctrine faithfuly portrays the ideas of Jesus Christ or the will of God, but modern catholics (well, at least the ones I know) dont seem hellbent of gulping down everything the vatican says or that they read in the bible as "absolute truth". This isn't the medieval age in which you'd be branded a heretic and burned for having your own interpretation, after all.
What I'm saying is that catholics often get dissed due to american society's general view of christians as bible-thumping wife-beating angry old people, and while the catholic church certainly isn't perfect or completely consistent with its doctrine, its still quite a bit more consistent then other groups out there, specialy the ones actively using the bible as a way to spread hatred.
Just my two cents on the matter, and I'm not even a catholic, mind you. I grew up in a protestant family, albeit a rather nice and open minded one.
