Go Your Separate Ways

We know Andrew Sullivan is upset with Pope Benedict. He's already slandering by dubbing him the "Grand Inquisitor." (Guess the Crusades will be starting up again. How about we re-start the Knights Templar?) Many American Catholics will just continue to ignore the church's teachings on abortion, contraception, human sexuality, etc. Why don't these people accept they will never get along with Rome and break off to form an American Catholic Church? Being a Lutheran I don't have any grasp as to why Catholics continue to belong to a church whose teaching they no longer profess. Just like the Catholic Church survived when the Greek Orthodox split off and when the Reformation tore apart Europe, a schism wouldn't seal Rome's doom.
