(The following post should not be misconstrued as expressing a lack of respect towards Rav Shlomo Zalman Auerbach, ztz"l. I lived around the corner from him for several years, spoke with him on a few occasions, and I have tremendous respect for him. He was justly renowned not only for his incredible knowledge, wisdom and saintliness, but also for his breadth and open-mindedness. Yet "open-mindedness" is a relative term, and he was nevertheless a product of the charedi world.)
