This comment perfectly describes the impasse between traditional authoritarian Catholics and progressives.  Precisely because your belief system is based on external authorities teaching the Catholic truth, and because they say they do, you reflexively assign the same kind of learning pattern to everyone.  I got over that one when I was seven years old.

 I can't speak for all liberals, but this is not how I absorb and integrate information.  My personal experience has been that on too many occasions given authorities are dead wrong and that includes bishops and priests and all the rest of the ontologically superior caste of Catholic authority.  All one need do is spend some quality alone time reading a decent history of the Church to discern how often the authorities have been invoking non-authoritative personal opinion as authoritative teaching.  I proceed by the mantra 'buyer beware' and that includes the Roman Catholic teaching magisterium.
