I have not found that the Spanish-speaking congregation fits into any stereotypical box. They like "modern" music, although their "modern" includes folk-devotional pieces that sometimes date to the 18th century. They don't always dress up (and when they do, it can be LOUD), but they all kneel, on the floor.
The Carismaticos are into hand-raising and audible prayer, but they're also some of the strictest in morals and most knowledgeable about the Faith.
Personally, I'm prepared to be happy with whatever Pope Francis does.
Well I wish Pope Francis would put out the word that Catholics DO NOT HOLD HANDS during the Our Father. He needs to tell his bishops to start cracking the whip concerning these very protestant practices. The key is to follow the priest. He does not hold hands with the deacon or anyone else during the Our Father and no one else should either! Damn, I get tired of seeing it!
There are a handful of Hispanic/Spanish speakers who often show up at our Latin Mass (out of 20-25 total parishioners) I’ve never known if they are there due to missing earlier NO-Español Masses — ours is the last Mass of any kind during the day — or if their preference is actually the Latin Mass. They do follow the lay rubrics carefully. On the issue of clothing, these particular ones dress reverently, but once there was a lady with a low-cut blouse who insisted (before Mass started) on taking off her outer sweater to the consternation of her (more conservative) husband/boyfriend(?) They actually ended up having somewhat loud words outside the church building.
