I think another way out (from RCC perspectives) is for them having stated in one place that these 'other Christians' they wrote about, were in "the Church", just not visibly Roman Catholic.
Yet at the same time the condemnations still stand,operating under seemingly different definition of just what The Church is --- as you went into some detail about. In the end, the bigots among Catholicism can find succor for their own personal religious bigotry, allowing them to consider it not bigotry at all --- even as they whine about how others "hate" and are "anti", and are "bigots", etc.
The mindset short-circuits meaningful discussions.
I spend more than half my time defending against personal & false accusations. It's like there is a crew who are desperate that no one ever hear me (or you) out. I wonder why? Could it be --- they know that some things (that they'd rather not have to defend) will be exposed?
Meanwhile, is the cause of Christ being bettered here among these disputations? I for one am not willing to conflate any Church with being in it's membership, or merely only in it's administration -- God, upon earth.
He is not us, and we are not [fully] Him, albeit His Spirit dwell within those whom He has baptized with His Spirit.
I think this "crew" would find it difficult to defend their assertions that all "Protestants" lie when their own false claims are exposed. Perhaps our time would be better spent in defending the gospel instead of our personal honor - which we already have experienced will be trashed regardless? That will then make their fight against God and we already know how futile it is to fight against Him.
