I hate that I'm doing this, but...bishops were in their own family kitchens and probably at least licked the cake beaters.  The real idiocy is asking bishops from another whole generation or two or three to research and analyze the Millennial+/-crowd.  Even younger bishops would not have experienced the sexual revolution, the drug culture, the techno-whacky intimacy/reclusiveness of this generation, nor would they have likely known different than male-dominated Catholic-centered family life, with good old mom staying home to bake those never ending cookies for her 11 kids. 

There is no common denominator between the leadership and Catholic newbies.  Many bishops would have grown up under the old paradigm of punishment unto Hell, and probably most still believe it.  Pope Francis has said many times that the meaningful encounter must be between Jesus and the seeker.  

Answering a survey can supply a degree of rationality, but I don't think there is common ground for understanding.
