I am impressed by a young priest in our parish who is busy teaching himself Latin, or at least enough to say the Mass. Every week we get a few more words in Latin (in the NO, of course).
There's another aspect of the liturgical language, and that's political. I go to Spain a lot, and they have long been squabbling over two minority languages, Basque and Catalan, which were really revived for political reasons. When the Mass was in Latin, this wasn't a problem, and only the homily would be in the minority language (although it usually wasn't, at that time). When the Mass went to the vernacular, then suddenly the entire Mass was said in these minority languages, for purely political reasons. It was abrupt and insulting to Spanish speakers (the majority of the congregation), and in many cases was done as an expression of the left-wing views of the clergy. It would be as if Mahony ordered that all Masses in LA should be in Vietnamese or some other language spoken in the diocese. In the case of Spain, this had even less cause, since everybody spoke Spanish and the revival of these minority languages as official languages was artificial and politically motivated. The imposition of these languages in the Mass was done for political reasons and to exclude.
I think that an unexamined aspect of the use of the vernacular in the Mass is the extent to which it aided in the politicization of the Church and its being dragged into left-wing causes in the 1970s.
Put at least the ordinary back into Latin. That won't prevent these groups from doing the propers in whatever language they wish or, obviously, the readings and the homily, but it will blunt the effect and provide at least some reminded that this is a religious act and a language is simply a vehicle for it, and not a political statement.

25+ years ago I had a great deal of business in Spain, so much so that I became a virtual commuter to Madrid and Andalusia. One time I took my wife with me and one of her bags got sent to Palma instead of Malaga when we changed planes in Madrid. Iberia found the bags and got word to me that they would be on a certain bus to the village we were in. I went to the bus station and no bags. My Spanish at that point was virtually non-existent and no one there spoke French, Greek or English...but there was an old priest there who spoke very nice Latin. I had majored in Latin in college and had a misspent youth in part as an altarboy in the Latin Mass days (it was a very ecumenical time!) so we spoke Latin. The bags were in the next town down the road and were sent back within an hour. Without the Latin Mass, we'd have never found our bag! :)
Good point about the politicization aspects of the vernacular languages. Mass is not supposed to be about dividing.
