“I care about what frum jews, particularly my personal rebbeim and their rebbeim, have been doing last year, the year before, and the hundreds of years before.
I am far more convinced by pointing to a posek from 100 years ago, than 1000 years ago. “
Well if you really want to go there, a century ago frum women in much of the world were NOT covering their hair. And there are three poskim within the past 100 years who said that was mutar.
“That is not how we do it. We follow our mesorah, as it has developed. We don’t do new things.”
No, it IS how we do it. Sometimes we DO do new things. Jewish women had not worn wigs for a thousand years when they started doing it again in early modern times. Most poskim said it was ok. And there are a lot of innovations in other areas with no precedent.
