You are very right, but what I am very much afraid of is a further splintering of the C&E, Cafeteria, CINO, Vat II generation, conservative and traditional divisions. The differences are very much there. I just have this fear that the argument over Mass is going to look a lot like the argument over the spelling of Channakuh.
Maybe I'm worrying over nothing, but there's going to be infighting and it's not going to help with evangelization at all.
Actually, I think - maybe too optimistically - that a lot of people go along with things as they are simply because they don't know any better or have never seen anything else. Some of them are surprisingly appreciative of a beautiful and correct Mass, regardless of what they put up with uncomplaingly every Sunday. I don't think they'd have trouble readjusting.
That said, there would be an entrenched group - particularly the scads of "ministers," mostly elderly women, who have been installed in American churches - who would be very difficult, but I think that in the long run, they'd respect the authority of the priest or bishop(assuming he bothered to exercise it).
As for the ultra-liberals, they've already left anyway, since they very publicly do not accept most of the teachings of the Church. Maybe it would be a good thing for them to stop sponging off the life, reputation and money of the real Church and go out and see exactly how far their meager and unappealing PC Unitarianism would get them.
