Sometime ago, conservative Republicans adopted the term "RINO" (Republican in Name Only) to describe members of their party who parted ways with their own party on any number of issues (particularly concerning the santity of human life). I think the time has come to adopt the term "CINO" (Catholic in Name Only) for those members of our Church who dissent from the teachings of the Magisterium. The following article shows typical CINO opinions:

We must remember that not all Catholics, particularly lay Catholics (but also an unfortunate number of priests and religious brother and sisters), speak for the Church. For authoritative statements of what the Church teaches, and how we as lay Catholics are to apply those teachings to our lives, we need to look to our parish priests, our bishops, and our Holy Father. It is better to follow the authority of the Magisterium than to imperil out own souls, don't you think?
We should also remember to pray for our wayward brothers and sisters, that they may come to know and love the truth.
