Anger is a bit hyperbole. But I went to 13 years of Catholic School (K included) and we were tested and tested on the mass and we had the entire mass memorized. Now I still can’t keep up with the changes. Latin was great when it was used for the Mass (I never experienced it) but Latin is no longer used so why not keep our great mass that we had.
I go to Latin Mass, it is great, problem solved.
