You mean like the way the connotation "Protestant" is by Catholics here?
I have rarely seen anyone say something about the Roman Catholic Church where they weren't specifically speaking of the Catholic Church, Latin Rite. I have seen many times where Roman Catholics use the proper name Catholic instead of the adjective catholic to refer to the first century church and we all know that that one HAD no universal Pope in Rome as well as lacking numerous doctrines and dogmas that the Latin Rite today claims were "always and everywhere believed".
It may be hard to deal with for some but using RCC or RC or Roman Catholic Church to mean what is formally called the Catholic Church, Latin Rite is just a quicker way to reference the same religion on an internet forum and hasn't been a problem but to a few. It's not meant as derogatory, no reason to get ones feelings hurt.
oh no!!! you forgot Peter, Linus, Cletus, Clement, Evaristus, ...silly you!
