bubka: I know that my Rosh Yeshiva told me that Oz Vehadar Levusha is good for scaring girls away from the mitzva of tznius, and he doesn’t recommend it to anyone.
He also once told my brother that although he doesn’t necessarily agree with R’ Soloveitchik’s hashkafos, he was still a huge talmud chacham and a gadol, and he has a tremendous amount of respect for him. He once heard a bachur in the yeshiva refer to him as JB, and he blew up at him for his lack of respect.
