That’s exactly what it is. They’re probably all a million years old anyway, and their children don’t go to church because their parents have driven them out by making it so meaningless.
Our TLM has doubled in attendance. This is at least in part because the Latin masses were often the only ones that kept on going and new people stumbled into them - and stayed.
At the same time, the situation made the TLM people more welcoming. Some of those groups were famous for being obsessed with the small things and also spent all their time looking for liturgical flaws in the priests. Things will be very different for the Church in the future. This will open up the TLM parishes and people will go to them by default because they may be the last ones standing.
Our tlm parish is doing well too.
