The liturgical debates are quite heated, but it shows people have VERY strong feelings about the liturgy, the liturgy being the expression of the church, a way of the church to pass on her beliefs to the parishoner.
That said, I will explain why many people end up in the Traditional Movment, saying(many times quite unfairly) Novus Ordo This and Novus Ordo that. Most people who are Traditionalists are people who did not start out going to the traditional mass, they either only known the Novus Ordo their entire lives, or went to the Novus Ordo after the old mass was supressed in stages between 64-70. Now for me, the matter of the missal itself is secondary, because I believe that even if the 62 missal was kept, it would have still had the same poor translation to English, and the rubrics of the mass where the priest is facing the people, the altar rails removed and having lay readers would have taken place by the 70s, so the church would largely be where it is today in terms of liturgy.
Now, on why people eventually end up in the SSPX, SSPV, in schism or Sede territory is because they finally had enough of the “renewal”. It is not these people one day and say “Oh I have a problem with the offertory” and leave. These people are sick of seeing the mass reduced to an almost Evangelical Portestant service externally, trying to get across to their children why the Eucharist is what is, while a small Army of EMHCs are on the altar, and trying to explain to their children what father says during the sermon is not actually what the church teachers. They are sick of having to slog though 45-60 minuites of banal music that sounds like the theme songs of commercials from the 70s and 80s, they are sick of being told they need to “get with the times” when they simpily request just an occasional classic Catholic hymn in English, much less Latin. THey finally reach their breaking point and start to parish shop, and find the liturgical and theological life in these parishes not much better, if not worse, then they often find, by accident, a parish that offers the Latin mass. Because Bishops are still too stingy with Indults, the chapels they go to the offer the Latin mass are in at best an illregular relationship with Rome, if not outright schism, but these people are hungry, hungry for tradition, hungry for just somthing to be reverent, somthing that they can identify as Roman Catholic, somthing of beauty. This is not to mention the many more people who silently siffer in their pews week after week, just to fill their weekly Sunday and day of obligation duty.
Now understanding this, often times when faithful Catholics go to chapels outside of the diocean structure, they develop a seige mentality, they see the structural church as apostate, and start to view the Novus Ordo as invalid(even a Novus Ordo celebrated in Latin with Tridentine rubrics), and in too many cases, view attending an indult as being invalid or sinful, and get further and further away from the instituional church. It doesnt need to be this way, but all too often it is. Pray that the civil wars over liturgy end one day, and the groups like the SSPX are brought full back into the fold, and Cardinal Ratzingers reform of the reform fully takes place when todays seminarians became pastors and restore elemnets of tradition.
