BP Totty: I’ve never been to an Agudah conference so what you say about mixed seating is news to me but what’s wrong? It’s not davening or learning. Do you ever sit mixed? On a bus? At the doctor’s office? Waiting at the DMV office? PTA night at your child’s yeshiva or other school functions? And the halacha for g’dolim 50 years ago is the same halacha today.
Having said that, there were many g’dolim who were against Agudah at the start because they were against any religious organizational structure where politics plays its ugly hand.
