The claim is that modern educated women need Gemora learning to support their emunah at the intellectual level they are.
It’s a silly claim, because there’s plenty of material which Bais Yaakovs offer which is on a high intellectual level without learning gemara. Speak to anyone beho knows something about BJJ.
You may be particularly unappreciative to the concept because it applies less to women in your community
Aside from that comment being arrogant and condescending, it’s blatantly untrue. There is certainly a big range of education level in our community (as there is in the MO community) but that range extends to law degrees and above. Yet, learning gemara is still unnecessary and therefore assur (self motivated learning is not assur, but mandated, structured classes are). Plus, as mentioned above, the Bais Yaakov system has managed to make a high level Torah based curriculum available for those who need it, without having to resort to learning gemara.
Bottom line: the success of the Bais Yaakov curriculum is a complete rebuttal to the claim that nowadays it is necessary to teach gemara to girls, and the only reason the MO do it is because they are too weak to fight the feminist elements among them.
