Dear Simple,
“Were Rav Avigdor Miller ztz”l and all the other Gedolei Yisroel wrong in putting meaning into it?”
“AllA?!? Who are the others? Doesn’t “putting meaning” into it mean, that it does not really have any meaning on it’s own? Whatever motivations Rav Miller had for the essay, is not my concern. I trust him, that he knew what he was doing. And, does any of this make the case that there should be some meaning associated with yeshivish clothing today?
