Did the Inquisition team (for lack of better term) initiate this dogma? And was it absent before that team started up?
I just see a conundrum here. Folks are trying to say that they're "Roman Catholics" but not of the "authority of Rome." No can do, unless they can oust the Vatican from the authority of Rome. Hey maybe Billy Graham would want the job? :-) The only practical choice is to step outside that mold. That's what the Greek Orthodox did. That's what the Protestants did. Or perhaps, what the sedevacantists (i.e. Roman Catholics who aver that no qualified person currently occupies the Papal seat) do.
I think that the Catholic church, if in fact it already really has not realized it or not, has broken up, and that there will be an American Catholic Church, in the future. I think Rome has lost its authority, office of the inquisition, notwithstanding.
That's tough to answer definitively. When the Inquisition was founded, the chief worry was, I guess, the Albigensian/ Cathar heresies, which had been a concern before the founding of the inquisition. So I suppose you could say that the Inquisition was the enforcement arm of the various Councels of the church that established catholic dogma between 300ad and 1100ad, and they are officially deputies of, and subservient to the Holy See. But I expect it would be pretty silly to maintain that the Inquisition wasn't generating policy behind the scenes.
