What seems to have happened was that the liturgical convulsions following the council came in at the same time as secular American society was experiencing the volcanic eruptions of the counter-culture. Bad taste, vulgarity, a certain giddy and fuzzy quality to communal gatherings, and silliness in general began creeping in. As "encounter group" psychology spread through the clergy a ridiculous subjectivism followed. The Church in America, in many places, became hostage to some of the worst and most annoying elements within the Catholic community - liberal flakes.
We are seeing the deep damage now.
