You bring up good points Tommy.
There’s a bit of a difference in being silent “because we ought to” and being silent out of holy fear and trembling, as they used to say.
The Church is not a museum. It’s a living, breathing organism.
We don’t know for sure if it would anger the Lord to hear people greeting and speaking to one another in joyful recognition and thankfulness, or whether He would be glad we were a happy and close community.
There has to be a middle road, and pointing fingers either way really doesn’t satisfactorily answer these issues.
I often wonder why people insist on starting these threads…
when the obvious solution is to gather many like-minded parishioners and have a calm, respectful conversation with the pastor. Ask…*Father, can something be put in the bulletin or perhaps mentioned in the announcements or preached about observing more quiet in the Church before the start of Mass or keeping loud conversation to the Narthex?
*
Then let him answer and respect that he’s in charge.
That’s the only thing that matters. Discuss with the only person who can change the dynamic if people think it’s so awful. Many priests don’t mind it. Some insist on reverent quiet.
Find out how your priest wants to handle it or if he even thinks there’s something to “handle”.

Having tons of people weighing in with “Yeah, I hate it too” hardly seems to be working for anyone.
