Our old parish in MN had been involved, but for some reason wasn't doing anything with it by the time we arrived. I seem to remember some kind of "home church" mentality, but the thing that most struck me about it was the stubborn hatred for any Latin music, for Tradition, or for the old ceremonies. They were responsible for removing the black cassocks and white surplices of the altar boys and replacing them with slouchy, dingy "robes," altar girls, and a lot of other post-V II stuff. Wish I could be more help...
You’ve at least confirmed some of my suspicions! Thanks!
