Joseph, the famous Artscroll biography on Reb Yaakov Keminetzky ZT”L by jonathan Rosenblum came for the most part from the research of Reb Nosson Kaminetsky. I do not know how he’s viewed by the “oilam goilam”, but I do know that Rav Shmuel Kaminetky Shlit”a has his brother’s book freely available for perusal in his house. I see Rav shmuel Kaminetzky Shlit”a in the Yated all the time, and to get your picture in the Yated center pages you need to be a recognized gadol, a Rebbe, or a gvir. The hakdama to the 8th volume of igros moshe mentions that Reb Moshe Feinstein’s great grandmother attended a gemara shiur with the Tzemach Tzedek. She sat in the back. Reb Itzele Volozhin’s daughter was well-learned, as the Torah Temimah writes in his Mekor Baruch. Last time I checked, all yeshivish mesoras went back to Volozhin. Finally, RNK has a source from an eyewitness that Rav Aharon Kotler’s wife learned gemara. No matter how he’s viewed, it’s not an opinion- it’s an eyewitness account.
It is clear that the accepted psak for generations was that teaching them Torah is like teaching them tiflus. It is clear from the Chofetz chaim that something has changed, although he does not say to teach them gemara. It is also clear that yechidos learned gemara (1st wife of Netziv, grandmother of Reb Moshe Feinstein ZT”L, wife of Reb Aharon kotler ZT”L. Nobody in the velt (except Rav YB Soloveitchik) mattirs directly teaching women gemara, except out of town as part of a joint class. But the best seminaries in Israel for the top girls live on the edge here. They’re not learning Reb Chaims but they are learning heavy intellectual machshava material (Rambans, Maharals, Michtav Me’eliyahu, etc) which can be considered Torah SheBaal Peh.
I assume the same Reb Moshe by women’s Tzitzis would apply here as well- if it’s done lesheim shamayim, it’s ok for yechidos. If it’s done for rebellion, then it’s Torah Lekanter and is an aveirah chamurah.
According to many shitos in Hilchos shechita, nashim daatan kalos just means that they get squeamish.
True story from a friend of mine who now runs his own place- one year a yeshiva was learning Yevamos. The wife of an avreich asked him to explain what he’s learning. He starts explaining the cases in yevamos he was learning. Every case in Yevamos had a high tragic body count, and soon his wife started crying. This guy couldn’t believe it, and told my friend about it. My friend started laughing, assuming his wife was tougher than that. So he comes home and tells his wife the story, laughing at the squeamishness of the first guy’s wife. Soon enough, his wife’s crying too, and my friend says “Never mind”.
