I don't believe he is referring to mob mentality so much as the restoration of authentic customs. To cite an example, in looking over some parish photos from the early 80s, I was surprised to see the children holding felt banners as they entered the church to receive the Sacrament of Confirmation. Someone explained that for a while the Church tried to emulate the Latin Church. They have now restored the practice of Chrismation at the time of Baptism.
"I don't believe he is referring to mob mentality so much as the restoration of authentic customs."
That's the thing. Perhaps I'm simply missing it, but he seems to imply that there is a sort of extreme, forced de-latinization going on the eastern Catholic churches.
What in the wide world of sports is he talking about? Have you seen any severe, unpopular changes to enforce or restore eastern traditions in your church? I sure haven't seen them in mine. My church and Priest are fairly conservative with regard to traditions, but I'm sure not hearing complaints about that conservatism.
Orientalium Ecclesiarum specifically required eastern Catholic churches to follow their eastern traditions, and to restore those traditions where they were no longer being practiced. I'm just not seeing how implementing that directive would be controversial or problematic given that it's been roughly 40 years since that document was promulgated.
