I hope you are right -- I think you may be. My wife & I travel to France frequently and I am struck by two things:
1) the moribund atmosphere of most parish churches in France (Paris & the provinces alike); and
2) the vibrancy of the FSSP and SPPX churches.
I am also struck by wide range of people involved in the traditionalist movements in France. In America the traditionalists tend to be extremely clannish, defensive, and parochial. In France you find a much lower proportion of loonies among them. When I made the Chartres pilgrimage several years back I soon found myself hanging out with the French chapters rather than the Americans. They were less likely to spend the entire day arguing about Fatima.
Next time in France, look at the large families, the ones with three and four and five children.
Those will be the ones you see in the churches, among the young people. You will find many empty churches with old people in them, still faithful as things fall apart. But where you find large families, there too will you find The Faith, alive, and growing as it always has.
Even in the worst deluges, God always leaves a remnant from which the new tree grows.
