Mr. Nu there are very valid grounds to strongly disagree with what you write, as the Rebbe did. He encouraged women’s learning in today’s day where they are fully educated in secular matters (which already teaches them tiflus) so they should have an equally strong Torah education, and can learn whatever they want. Well I guess they could always learn whatever they want – they can be TAUGHT whatever – even gemara. But again depends who you follow.
If the tiflus quote applies to any Torah shebaal peh then the only ones who hold of that today are the Satmar.
But obviously halacha and hashkafa come first which is why even most lubavitcher high schools don’t have a gemara class.
