I’m not sure precisely who you are throwing under the bus, but as you use the plural, it is an indeterminate number of individuals, and the terms that you use (historical revisionist and schismatic) cast rather wide nets. Are you referring only to the conversos in Spain, or multiple things—this has been a wide-ranging thread.
In complex situations, appologizing without sorting out details is sometimes appropriate, and sometimes not. That the spanish monarchs had a virtual stranglehold over the Church within their domains through most of the 16th through 18th centuries may or may not be an insignificant fact—yes, they are Catholics, and so the Pope may apologize on their behalf, and yes many of their decisions may have clashed with Catholic doctrine, but if the subject is “how consistent has the papacy been on teaching” rather than “have some Catholics been really nasty” the distinction may be important.
The fallible part does include a teaching authority that is an authority, and is, under certain specific defined circumstances, actually infallible in what it teaches, which does raise some questions that need to be addressed, and so distinctions in addressing these questions may be appropriate. Authorities also come in various gradations—at times making distinctions is helpful, at time, not.
I may or may not agree that the posts to which you are referring might be erroneous, or at least more happily phrased, but tossing out the words and phrases like schismatic and more catholic than the pope without specific referents may muddle things further.
I did not want to name names for the reason I thought it would not be contructive.
Those who attempted to deflect blame of the Chuch (Component 1 of the Church, not 2) for Ethnic Cleansing of the Jews from Spain, et al, know who they are.
It was a sin to cast the Jews -— who remain the Apple of God’s eye, even in their denial of Christ, by the way -— off into muslim lands, to force them to live lies, or to convert at the sword.
I, for one, stand with John Paul and the Church’s stated position, not with the Schismatics — and that is what they are.
