It is nostalgia to the extreme.
Yes. The baby boomers still run the world and their nostalgia hinders them perceiving true reality. In trad circles, this filters down to the younger generations who, having no connection to the past, and especially no connection with the V2 revolution, leave tradition and go to the indult and their local parish, because their trad parents/grandparents who should be viligant, see a latin mass and emotionally give their approval, or passively say nothing.
The V2 generation of catholics accepted V2 wholeheartedly. They had the full truth and dropped it by the side of the road because they wanted novelties.
The 2000s generation of trad catholics have the truth, but don't understand what they have.
