are baal teshuvah and gerim so obsessed with showing how tznius they are?
Because we have zrirus for mitzvos and Torah.
In my opinion it is similar to someone saying ,”HEY GUYS LOOK I EAT KOSHER. LOOK? SEE?” it’s nice that they are tznius, but i most certainly don’t think it’s something to brag about.
Never EVER have I met a BT or convert who was braggy. On the contrary, all of them are always erlich and humble.
