For one thing the vernacular is not really a big issue with RC traditionalists; it’s the radical alteration of the words and structure of the Mass, the ascetic laxity, and the theological point of view taught by Vatican II and the much more radical theological liberalism that became rampant in the name of the spirit of Vatican II. I don’t think any traditionalists would really want the Tridentine Mass translated into English, but they would not complain about that nearly as much as the Novus Ordo. RC traditionalists don’t like the Novus Ordo in Latin any more than any other Novus Ordo.
Also, the vernacular versus Latin issue was a major point of contention during the Protestant Revolt, and I think most “Latin exiles” recognize that the Divine Liturgy was never said in Latin and that there is a longer tradition of saying it in the vernacular than there is in the West.
I also think that most “Latin exiles” (and I include myself in this category - I was a Roman Catholic traditionalist who fell in love with Byzantium) would much prefer the Liturgy in a sacred language, Greek or Slavonic. We’re not adamant enough about it to riot in the middle of the service as the Greek congregation did less than a week ago when their Metropolitan started reading the Old Testament reading in demotike rather than katharavousa, but I would rather learn Slavonic than continue having Liturgy in English. That being said, the liturgical problems in the East (the RDL, the use of English, the pews, the see-through iconostases, and the rampant Latinizations) are of a totally different order than the liturgical problems in the West where I have trouble even recognizing that I am in a Catholic church. (I’m the old-fashioned type of body-soul composite that still needs sacraments and other visible signs to show me spiritual realities - I can’t go to a disco party where they hand out pieces of validly consecrated bread and receive the same spiritual nourishment that I do at a Traditional Liturgy.)
Most “Latin exiles” (not including myself) would probably prefer the Tridentine Mass to the Divine Liturgy - they are Catholics of the Roman Rite, after all, and they have a right to their own spiritual tradition. But one can go from one to the other and still see the same faith, and experience the same bond of faith with the parishioners of either church. That’s not something I can do at a Novus Ordo. We both pray for the Pope of Rome, but there is no visible bond of faith between myself and the congregation at a Novus Ordo Mass, and I feel as out of place as I do in a Protestant congregation. I suspect other Traditionalists experience the same thing, and are hospitable enough guests not to complain about the use of English at Divine Liturgy.
