oomis1105-Your Grandmother may not have formally learned out of a sefer, but she definitly learned Torah experiantially-and by living it. That’s how most women learned that which they needed to for centuries in order to preserve klal yisroel-and until the Bais Yaakov movement.
If someone is not educated with authentic Torah values then their perception of “Orthodox” Jews can not be accurate, because they are not taking an honest look into what it means to be a a Torah true Jew. If these people who voice their disdain about Orthodox Jews would spend a full week in a frum ehrliche yid’s home, they surely would walk away amazed at how we conduct our lives. It’s a lot easier, and much less guilt ridden to not look at what is emes, and to judge Torah Judaism by those who they wish to judge and not on the Torah’s terms. If they would, it would obligate them, get to their essence and conscience and that would be too overwhelming.
