How did the liturgical abuses get started?

Adoremus has posted selected quotes from the past on specific problems raised in Redemptionis Sacramentum

After reading many of these quotes from self-proclaimed liturgical experts, it's really difficult to maintain a balanced composure. One may react, and I believe rightly, with disgust at these people who have had a major influence on the abuses we have witnessed for years.

Another truly sad aspect of all of this is that far too many priests and 'liturgy directors' or committees read such books and articles as if they were true. Again, this is a direct result of a failure to educate and teach the faithful.
