Uhhh ... sounds like you trying to start something. I intended nothing of the sort. But I will say with confidence that Catholics do not call themselves Christians and Christians do not call themselves Catholic. [Note the capital C -- I don't want to start a dialogue about the universal use of the adjective "catholic" as used in the Apostles Creed.]
started a long while ago, and not by me, and no sarcasm intended. I was born-and-raised Catholic. Continued in the RCC, until I started reading the Bible.
