I am not aware of  a time when that happened. I do know that  the educational levels of Catholics in the west improved significantly throughout the 20th century. Able to read and study on their own, many Catholics concluded that much of what the church taught was not "truth", but opinion  based on the mores of the eras in which they were defined. They saw that the church had failed to recognize much of what has been learned since then, nor has it taken it into account, continuing to cling to ancient understandings - and prejudices.  But, the key factor was the hierarchy's failure to listen to the sensus fidelium on ABC,  the prime example of the overall failure of the hierarchy to recognize that the Holy Spirit does not speak through a handful of men, but through the entire church.  The crackdown on theologians who recognized that the church must open itself to the HS was part of the impetus for the growing divisions.  Many gave up hope that the few would ever listen to the  Church.
