It does seem to depend on the discussion with our Catholic friends as to the status of Luther.
That Luther must have hit a sore spot is evidenced by the Counter-Reformation. Hence, there was, and still is, much wrong with the RCC.
For you too, I'm thinking.
I’ve witnessed a particularly vehement apologist deny that there was ever such a thing as the Counter-Reformation, that Protestants had nothing to do with it.
