Blame it on the Sisters of St. Joseph of Margaret Sanger.

You say you want a revolution…
Everyone likes to blame the baby-boomers for all the liberalism we have become accustomed to in the Church today. Few realize it all started long before the boomers were even capable of expressing a revolutionary thought. How many young people today understand that the push for liturgical reform, modernizing the liturgy, and using the vernacular was a desire experimented with before the Council? How many people realize that it was Pius XII who called for women religious to modify their habits to adapt to the demands of modern life, such as the nuns who drove cars or worked in medicine? (Although later, many modified themselves out of the habit entirely.)
When I was in grade school, the nuns taught us - way back then - songs such as ”Kumbaya” - and we listened to the Congolese Missa Lubaand had to sing Negro spirituals. (Although black kids in the class were disciplined until they spoke without an “accent”.) I think it was probably the missionary sisters who came back to the motherhouse with stories of how fervent the African Catholics were, and how much the native people enlivened the liturgy with their exuberant participation and singing, which motivated the sisters to jump on board as regards the reform of the liturgy. When Vatican II came along, it was a dream come true for a good share of them.

I di’n't know nothin’ ’bout Civil Rights.
Then in the very late 1950’s, early 1960’s the nuns began to get deeply involved in politics - in and through the Civil Rights movement. (Of course, we had a Catholic President then as well.) The nuns marched alongside priests and ministers, protesting segregation and demanding the right to vote for black people. Without doubt it was a good thing, except, in the mid-’60’s the revolutionary spirit suddenly crept into the convent, along with a strong feminist understanding of power, individualism, and independence. Which happens to be another reason why we have the American Catholic Church we have today.

“Yes Sister, whatever you say Sister!”
So don’t put all the blame on boomers - blame the Sisters of St. Joseph of Margaret Sanger, and the other storm trooperorders who taught us. (After all, many of them were from the same generation as my parents and your grandparents.) Funny, what they subsequently failed to realize, their habits spoke louder than words.
(Disclaimer: The religious women who taught us are to be highly praised for their sacrifice and dedication, no doubt about it. Just as they ought to be commended and honored for their heroic work in the Civil Rights struggle. This has been my personal reflection on what, in part, may have contributed to the decline of religious life in the U.S., as well as an offering towards understanding why the American Catholic Church got to be so liberal.)
