“Whatever Luther style spin you want to put on it, be my guest.”
That seems both harsh and inaccurate, Luther created a new religion, the SSPX is far more like the Orthodox that the Protestant and even that isn’t correct, as Rome is treating them as being neither schismatic nor heretical. Why you choose to be “more Catholic than the Pope” in this regards is a puzzle.
I think a significant percentage of these folks will accept what's been arranged already and the balance clearly match what I think of them, just another means to fracture the Church. Whether that's their intention or not is moot. If I'm wrong, I'll be very happy.
