I think the big thing here is that Catholicism has a clear set and well defined dogma, but it’s not just that. Converts tend to have the dogma but they lack more or less everything else about Catholicism. That includes the community values (for better or for worse) and the folk traditions. Instead they tend to double down on the aesthetic and general cultural understandings.

In short, they believe monks should be Benedictine and not a smiling Franciscan sharing his meal with a homeless person or a Jesuit studying the stars to bear witness to their glory.
