Say you were living through Vatican II, and saw CLEARLY and had countless evidence that the Novus Ordo Mass is doing grave harm to the Faith, and to souls. As you see it, disobedience to your local priest -- even the Pope -- is warranted, since obedience is beneath Faith, Hope, and Charity.
You are convinced you are "in the right" to leave your Parish, and stay home until a Traditional Mass location is formed near you.
Now pretend you and a bunch of like-minded Catholics start meeting up for discussions -- to coordinate, support each other emotionally and spiritually, plan to set up a Mass center, etc. and you pick Joe's Coffee House, since Joe is one of your members.
Now 2 months later, someone named Alice from your old Parish shows up at Joe's Coffee House -- not as a friend, but as a "missionary" to try to "bring back the lost sheep".
Since the period of time post-Vatican II is full of confusion, and things that should never happen, you realize that it's not going to help anything to allow Alice to preach about obedience, the normal attitude towards the Pope, etc. -- it might confuse many simple Catholics, and ultimately do harm to souls.
So Joe decides he must kick Alice out of his coffee shop, at least until they get their Mass center set up.
Well, I am Joe, and Caminus is Alice. Vatican II is the new SSPX-Rome Deal. And so forth.
