Okay seriously, gossip aside. We should ask ourselves how we have come to this .
I think it's a weird duplicitous world where we have such luxury gashmius then such level of frumkeit .
Ultimately, you need yiras shamayim and a belief In God as
@AsherO just said . How can you hand Torah without yiras shamayim?
My father would tell me of the yidden who either by communism or the Holocaust stopped being frum, they'd learn gemara on Shabbat while smoking a cigar (Not sure if this was the actual story or a mashal) but anyways, that's the hellinism
With Torah lishmah, honestly all this hiddur in the expensive esrogim, ataras, shtreimelech etc .. (yes, we pick on the women for long sheitels but your massive $7000 shtreimel is the same hubris)
Ultimately, indeed talking in shul belies what it means to be a yid.
Fear of heaven, respect of the shul, the prayers etc beyond that, why build fancy shuls? Who is gaining from a fancy shul ?!? Not God if they talk... Just the people going there can puff their chest out and say "we built such a beautiful shul"
