Perhaps, we do not choose to adopt an "ism", as you put it. A Catholic who is not a member of any cult or ill formed association, but a person who has not lost the use of his reason and ability to think critically might better sum things up.
Folks such as yourself, have been captured by myths, and must always find a category into which you can place this or that individual, who has anything to say which does not comport with the sectarian narratives of the past three or four decades.
Ah, yes, you are too complicated and unique to be placed in a category... we should make up a new word JUST FOR YOU because you are THAT SPECIAL.
Get over yourself, man! You're not "above it all", however much you claim to be.You deny man's rational nature, which is able to abstract, categorize, and know the essence of things. Why do you have a problem with categories or "hat racks" to categorize various nouns? (people, things, ideas, movements)? It's basic rational human nature you have a problem with. It's one of the things that separates us from the animals.
If there's one type of "anti-Novus Ordo" type that annoys me more than any other, it's those who seem to be sympathetic to the movement, but they want to be aloof from it. Those who say, "I'm just Catholic" as if all those who accept the label "Traditional Catholic" are some kind of low-end, Rent-a-Center patronizing, lotto ticket buying, pawn shop using, cheap beer guzzling, sports team rooting, low-credit-score having, lots of TV watching, fake fingernail wearing, tattooed, nose-pierced, Wal-Mart cashiers.
In one statement or wave of the hand, they write off ALL the Traditional Movement, from the sedevacantists to Archbishop Lefebvre to Fr. Bolduc and the whole lot of them. They consider themselves smarter than ALL of them. And even if they deny it, it's still just as true. You can't reject the whole Trad movement and somehow still believe that any of them were superior to you. That would be empty talk.
We don't accept the label "Traditional Catholic" because we're partisan, have a team or gang mentality, love division, or any of that BS. It's because it's a label that does a job: it reflects a reality: we all hold a certain position on the Crisis. Like any element of LANGUAGE used by rational creatures, language serves as a shorthand abstraction to convey a certain reality.
Why don't you go further and call yourself "Christian" instead of Catholic! Come on, don't give any ground to those Protestants. Take back the name! Let's pretend the Prots didn't take over much of the Western world.
Oh, but if you call yourself Christian, people will assume you're protestant, won't they? And if you call yourself "Catholic", they're going to assume you're mainstream (novus ordo) Catholic. That's the REALITY, like it or not. You can kick against the goad, but reality is reality.
That's why the new 3rd, 4th, and 5th gender pronouns aren't taking off -- at all. Those "new genders" are only manifestations of mental illness existing solely in the brains of a handful of mental patients. They aren't real, so we don't need any new words to reflect a new reality.
