Saying that a woman is allowed to learn but a woman is not allowed to be taught is essentially saying she’s not allowed to learn. You can’t learn anything, especially Gemara, without a teacher. If she is allowed to learn when she wants to learn, then obviously she is allowed to be taught. Saying otherwise is illogical
Perhaps if a woman can learn on her own, then it is permissible. If she needs to be taught, then it isn’t permissible.
If you are saying it is impossible for a woman to learn gemora on her own, I disagree with you. There are woman who have the intellect to do so.
