This kind of thing is often heard in Indult circles.
The fact is, Vatican II was a complete break with Tradition. After many decades, a new religion developed such that "Novus Ordo Catholics" actually believe and act differently than real Catholics. IN EVERY MEASURABLE WAY.
Therefore we must be specific when we say what we are. If you WANT someone to assume you're a Novus Catholic -- worldly, birth control using, liberal, and all that, then BY ALL MEANS say you're just Catholic.
I like to distance myself from Vatican II as much as possible, so for the sake of accuracy and truth I say I am a Traditional Catholic.
And yes, that's with a capital T. Indult types are the ones who say, "I'm traditional but not with a capital T if you know what I mean."
Yeah, I know what you mean. Which is why I go the opposite direction -- I'm Traditional Catholic with a CAPITAL T.
I am TRADITIONAL CATHOLIC first and foremost. I never sold out to the Conciliar religion. I am faithful to the Church's Tradition.
